Refactor: Eliminate duplicate types - Use handler types directly

- Deleted templates.CollectionDetailData - using templates.CollectionData everywhere
- Deleted templates.BookData - using handlers.BookInfo everywhere
- Deleted templates.DeviceData - using handlers.DeviceInfo everywhere
- Deleted templates.ProgressItemData - using handlers.ProgressWithMedia everywhere
- Deleted templates.convertDevices() helper - Use handlers types directly in templates
- Enhanced handlers.ProgressWithMedia with device metadata fields
- Added handlers.getDeviceIcon() helper
- Updated all templates to import handlers package
- Cleaned up unused imports

This aligns codebase with templ's design philosophy (use Go types directly, no parallel type system)

+# Type Duplication Refactoring Plan
+
+**Document Purpose**: Consolidate duplicate type definitions across templates/ and handlers/ packages to align with templ's design philosophy and reduce maintenance burden.
+
+**Status**: Planning Phase
+**Last Updated**: 2026-02-12
+**Separation from**: IMPLEMENTATION_EXACT.md (this is independent refactoring)
+
+**Core Principle**: **API wins** - When there's ambiguity between template types and API/handler types, the API/handler types take precedence.
+
+---
+
+## Executive Summary
+
+**Problem**: Codebase maintains parallel type systems:
+- `templates/types.go` - Template-specific types
+- `handlers/*.go` - API response types
+
+**Core Principle**: **API wins - when in doubt, API/handler types take precedence**
+
+### Why "API wins"?
+
+1. **API is public contract**: Handler types define your public API surface - these are more stable
+2. **Templates are presentation**: HTML templates can format any Go type - they're flexible
+3. **Single source of truth**: One authoritative type definition vs two parallel definitions
+4. **Json serialization**: Handler types already have `json:"..."` tags for API responses
+5. **Future API clients**: If you add mobile apps or CLI tools, they need handler types anyway
+
+### Trade-offs
+
+**Pro**: Simpler codebase, one type to maintain, automatic API/HTML consistency
+**Con**: Templates may have unused fields visible in scope (acceptable - templ handles this well)
+
+**Impact**: 
+- ~40 lines of duplicate type definitions
+- Unnecessary conversion functions
+- Maintenance burden (update 2 places for 1 change)
+- Violates templ's design philosophy
+
+**Solution**: Use handler types directly in templates, eliminate template-specific duplicates.
+
+---
+
+## Current State Analysis
+
+### Duplicates Found
+
+| Template Type | Handler Type | Overlap | Action |
+|---------------|---------------|----------|--------|
+| `DeviceData` | `DeviceInfo` | 90% | **DELETE** DeviceData |
+| `BookData` | `collections.BookInfo` | 100% | **DELETE** BookData |
+| `CollectionDetailData` | `CollectionData` | 100% | **DELETE** CollectionDetailData |
+| `ProgressItemData` | `ProgressWithMedia` | 70% | **MERGE** (different fields) |
+| `QueueItemData` | `QueueItemResponse` | 60% | **KEEP** (template uses subset) |
+
+### Already Using Handler Types (Good Patterns)
+
+✅ `Conflicts` template uses `handlers.ConflictDetailResponse`
+✅ `Queue` template uses `handlers.QueueItemResponse`
+
+**This is the pattern we want everywhere.**
+
+---
+
+## Refactoring Plan
+
+### Phase 1: Eliminate Complete Duplicates
+
+#### 1.1 Delete CollectionDetailData
+
+**Files to Modify**:
+- `templates/types.go` (lines 26-32) - DELETE struct
+- `templates/collection_rules.templ` (line 3) - Change signature
+- `templates/collections.templ` (line 213) - Change signature
+
+**Changes**:
+
+**Delete** from `templates/types.go`:
+```go
+type CollectionDetailData struct {
+    ID          string
+    Name        string
+    Description string
+    Color       string
+    Icon        string
+}
+```
+
+**Update** `templates/collection_rules.templ:3`:
+```templ
+// BEFORE:
+templ CollectionRules(user User, collection CollectionDetailData) {
+
+// AFTER:
+templ CollectionRules(user User, collection templates.CollectionData) {
+```
+
+**Update** `templates/collections.templ:213`:
+```templ
+// BEFORE:
+templ CollectionDetail(user User, collection CollectionDetailData, books []BookData) {
+
+// AFTER:
+templ CollectionDetail(user User, collection templates.CollectionData, books []collections.BookInfo) {
+```
+
+**Test**: `go test ./templates/...` after template regeneration
+
+---
+
+#### 1.2 Delete BookData
+
+**Files to Modify**:
+- `templates/types.go` (lines 34-39) - DELETE struct
+- `templates/collections.templ` (line 213) - Change books param
+
+**Changes**:
+
+**Delete** from `templates/types.go`:
+```go
+type BookData struct {
+    MediaItemID    string
+    Title          string
+    Author         string
+    CoverImagePath string
+}
+```
+
+**Update** `templates/collections.templ:213`:
+```templ
+// BEFORE:
+templ CollectionDetail(user User, collection templates.CollectionData, books []BookData) {
+
+// AFTER:
+templ CollectionDetail(user User, collection templates.CollectionData, books []collections.BookInfo) {
+```
+
+**Test**: View collection detail page, verify books display correctly
+
+---
+
+#### 1.3 Delete DeviceData and ConvertDevices
+
+**Files to Modify**:
+- `templates/types.go` (lines 48-57) - DELETE struct
+- `templates/devices.templ` (line 3) - Change signature
+- `internal/router/helpers.go` (lines 46-67) - DELETE function
+- `internal/router/frontend.go` (lines 161-169) - Remove conversion
+
+**Changes**:
+
+**Delete** from `templates/types.go`:
+```go
+type DeviceData struct {
+    ID            string
+    DeviceName    string
+    DeviceType    string
+    SyncEnabled   bool
+    AutoSync      bool
+    SyncFrequency int32
+    LastSync      string
+    LastSeen      string
+}
+```
+
+**Delete** from `internal/router/helpers.go`:
+```go
+func convertDevices(deviceInfos []handlers.DeviceInfo) []templates.DeviceData {
+    // ... entire function (lines 46-67)
+}
+```
+
+**Update** `templates/devices.templ:3`:
+```templ
+// BEFORE:
+templ Devices(user User, devices []DeviceData, pendingRegistrations []PendingRegistrationData) {
+
+// AFTER:
+templ Devices(user User, devices []handlers.DeviceInfo, pendingRegistrations []PendingRegistrationData) {
+```
+
+**Update** `templates/devices.templ` template logic:
+
+Find these patterns and update:
+```templ
+// BEFORE:
+if device.LastSync != "" {
+    <span>{ device.LastSync }</span>
+}
+
+// AFTER:
+if device.LastSync != nil {
+    <span>{ device.LastSync.Format("2006-01-02 15:04") }</span>
+}
+```
+
+**Update** `internal/router/frontend.go:161-169`:
+```go
+// BEFORE:
+deviceData, err := cfg.DeviceHandler.GetDevicesData(c)
+if err != nil {
+    return c.HTML(http.StatusInternalServerError, "Error loading devices")
+}
+pendingData, err := cfg.DeviceHandler.GetPendingRegistrationsData(c)
+if err != nil {
+    return c.HTML(http.StatusInternalServerError, "Error loading pending")
+}
+deviesList := convertDevices(deviceData)
+pendingList := convertPending(pendingData)
+
+// AFTER:
+deviceData, err := cfg.DeviceHandler.GetDevicesData(c)
+if err != nil {
+    return c.HTML(http.StatusInternalServerError, "Error loading devices")
+}
+pendingData, err := cfg.DeviceHandler.GetPendingRegistrationsData(c)
+if err != nil {
+    return c.HTML(http.StatusInternalServerError, "Error loading pending")
+}
+// No conversion - use handler data directly
+```
+
+**Test**: Devices page renders correctly with proper date formatting
+
+---
+
+### Phase 2: Eliminate Remaining Template Types
+
+#### 2.1 ProgressItemData → Use ProgressWithMedia
+
+**Current Issue**:
+- `handlers.ProgressWithMedia` exists as API response type
+- `templates.ProgressItemData` duplicates it with minor variations
+
+**Decision**: **API wins** - Use `handlers.ProgressWithMedia` everywhere
+
+**Files to Modify**:
+- `internal/handlers/progress.go` - Update `ProgressWithMedia` struct
+- `templates/types.go` - DELETE `ProgressItemData`
+- `templates/progress.templ` - Use `handlers.ProgressWithMedia`
+
+**Changes**:
+
+**Add fields to** `internal/handlers/progress.go:ProgressWithMedia`:
+```go
+// ADD fields to existing struct:
+type ProgressWithMedia struct {
+    MediaItemID    uuid.UUID       `json:"media_item_id"`
+    Title          string          `json:"title"`
+    Author         string          `json:"author"`
+    CoverImagePath string          `json:"cover_image_path"`
+    Percentage     float64         `json:"percentage"`
+    CurrentPage    int32           `json:"current_page"`
+    TotalPages     int32           `json:"total_pages"`
+    LastReadAt     time.Time       `json:"last_read_at"`
+    Epubcfi        string          `json:"epubcfi"`
+    LastSyncDevice string          `json:"last_sync_device"`
+    DeviceName     string          `json:"device_name,omitempty"`      // ADD
+    DeviceType     string          `json:"device_type,omitempty"`      // ADD
+    DeviceIcon     string          `json:"device_icon,omitempty"`      // ADD
+}
+```
+
+**Update** `internal/handlers/progress.go:GetAllProgress()` to populate new device fields.
+
+**Delete** from `templates/types.go` (lines 99-112):
+```go
+type ProgressItemData struct {
+    // ... delete entire struct
+}
+```
+
+**Update** `templates/progress.templ:3`:
+```templ
+// BEFORE:
+templ Progress(user User, progressData []ProgressItemData) {
+
+// AFTER:
+templ Progress(user User, progressData []handlers.ProgressWithMedia) {
+```
+
+**Test**: Progress page displays device names and icons
+
+**Delete** from `templates/types.go` (lines 99-112):
+```go
+type ProgressItemData struct {
+    // ... delete entire struct
+}
+```
+
+**Update** `templates/progress.templ:3`:
+```templ
+// BEFORE:
+templ Progress(user User, progressData []ProgressItemData) {
+
+// AFTER:
+templ Progress(user User, progressData []handlers.ProgressWithMedia) {
+```
+
+**Test**: Progress page displays device names and icons
+
+---
+
+### Phase 3: Update Get*Data Functions
+
+**Issue**: Several handler functions return handler types but aren't used directly by templates due to conversion layer.
+
+**Files to Modify**:
+- `internal/router/frontend.go` - Remove conversions
+
+**Changes**:
+
+**Devices** (already done in Phase 1.3):
+- `GetDevicesData()` returns `[]handlers.DeviceInfo`
+- Template uses directly
+
+**Progress**:
+```go
+// frontend.go - update progress route
+protected.GET("/progress-page", func(c echo.Context) error {
+    // ...
+    progressData, err := cfg.Handler.GetAllProgressData(c)
+    // Returns []handlers.ProgressWithMedia directly - no conversion
+    // ...
+})
+```
+
+**Collections**:
+```go
+// collections.go - update to return handler types
+func (h *CollectionHandler) GetCollectionBooksData(c echo.Context) ([]collections.BookInfo, error) {
+    // Already returns BookInfo - just update template
+}
+```
+
+---
+
+## Summary Table
+
+| Phase | Files Changed | Lines Removed | Lines Added | Net Change |
+|-------|--------------|---------------|--------------|-------------|
+| 1.1 CollectionDetailData | 3 | 7 | 2 | -5 |
+| 1.2 BookData | 3 | 6 | 0 | -6 |
+| 1.3 DeviceData | 4 | 24 | 5 | -19 |
+| 2.1 ProgressItemData | 4 | 14 | 3 | -11 |
+| **Total** | **14** | **51** | **10** | **-41** |
+
+**Note**: QueueItemData already uses handler type (good pattern). Conflicts already uses handler type (good pattern).
+
+---
+
+## Testing Checklist
+
+After each phase:
+
+### Phase 1.1 (CollectionDetailData)
+- [ ] View collection rules page
+- [ ] Edit collection rules
+- [ ] View collection detail page
+- [ ] Add books to collection
+
+### Phase 1.2 (BookData)
+- [ ] View collection detail page
+- [ ] Browse books in collection
+- [ ] Book covers display correctly
+
+### Phase 1.3 (DeviceData)
+- [ ] Devices page loads
+- [ ] Device cards display
+- [ ] Last sync/last seen dates formatted
+- [ ] Device type icons show correctly
+
+### Phase 2.1 (ProgressItemData)
+- [ ] Progress page loads
+- [ ] Progress entries show device names/icons
+- [ ] Percentage display works
+- [ ] Cover images display
+
+---
+
+## Rollback Plan
+
+If refactoring breaks functionality:
+
+1. **Git stash** changes before starting
+2. **Commit after each successful phase**
+3. **Revert individual commits** if needed
+4. **Keep conversion functions** commented out temporarily
+
+```bash
+# Before starting
+git stash push -m "pre-refactor-state"
+
+# After Phase 1.1
+git commit -m "refactor: delete CollectionDetailData, use CollectionData"
+
+# If Phase 1.2 breaks
+git revert HEAD
+# Continue with 1.3
+```
+
+---
+
+## Benefits
+
+### Code Quality
+- ✅ Aligns with templ's design philosophy
+- ✅ Single source of truth for types
+- ✅ Reduced code duplication
+- ✅ **API-first**: Handler types are authoritative
+
+### Maintenance
+- ✅ Update types in 1 place, not 2
+- ✅ Less conversion logic to maintain
+- ✅ Clearer data flow
+- ✅ **Template changes automatically get API updates**
+
+### Consistency
+- ✅ All templates use handlers types (like Queue/Conflicts already do)
+- ✅ API and HTML use same type definitions
+- ✅ 41 fewer lines of code
+- ✅ **"API wins"** principle eliminates ambiguity
+
+---
+
+## Future Considerations
+
+### For IMPLEMENTATION_EXACT.md
+After this refactoring, adding `AuthToken` to devices is simpler:
+- Add `AuthToken string` to `handlers.DeviceInfo` struct
+- Add to `GetDevicesData()` function return values
+- Template automatically gets it (no conversion layer)
+
+This **solves the critical issue** found in IMPLEMENTATION_EXACT.md analysis automatically.
+
+### For New Features
+- Define handler types with json tags first
+- Templates use same types directly
+- Only create template-specific types for:
+  - Computed/derived fields not in API
+  - Combining data from multiple sources
+  - Simplifying complex nested structures
+
+---
+
+## Execution Order
+
+1. **Run tests** to ensure baseline: `go test ./...`
+2. **Create feature branch**: `git checkout -b refactor/types-consolidation`
+3. **Execute Phase 1.1** (CollectionDetailData) - DELETE template type, use API type
+4. **Commit and test**
+5. **Execute Phase 1.2** (BookData) - DELETE template type, use API type
+6. **Commit and test**
+7. **Execute Phase 1.3** (DeviceData) - DELETE template type, use API type
+8. **Commit and test**
+9. **Execute Phase 2.1** (ProgressItemData) - DELETE template type, enhance API type
+10. **Final commit and test**
+11. **Update IMPLEMENTATION_EXACT.md** to reference handler types only
+
+**Total Estimated Time**: 2-3 hours with testing
+
+**Key Mindset**: Every change removes a template type, never the reverse. API types are authoritative.
+
+---
+
+## Questions for User
+
+1. **Progress template updates**: Since we're using `handlers.ProgressWithMedia` (API type) in templates, any template formatting changes (like date formatting) should be done in the template itself. Is this acceptable?
+
+2. **Testing**: Do you have automated template tests, or is this manual testing only?
+
+3. **Implementation plan**: Should I update IMPLEMENTATION_EXACT.md after this refactoring to reference `handlers.DeviceInfo` instead of `DeviceData`?
+
+4. **Json tags on handler types**: Templates don't need `json:"..."` tags - should we document that these are for API responses only?
