This commit migrates the frontend templates from the deprecated
/api/media-items/filtered endpoint to the new unified /api/media-items/search
endpoint and adds initial autocomplete support for the author filter.
**Endpoint Migration:**
- Changed library-select: /api/media-items/filtered → /api/media-items/search
- Changed search box: /api/media-items/filtered → /api/media-items/search
- All filter inputs now use unified search endpoint
- Pagination buttons updated to use /search endpoint
**Author Filter Autocomplete (Initial Implementation):**
- Added HTML5 datalist element (author-datalist)
- Added list="author-datalist" attribute to input
- Added Alpine.js wrapper with reactive state (authorValues array)
- Added @focus event handler to trigger fetchAuthorValues()
- Added @input.debounce.300ms for lazy-loading as user types
- Template x-for loop to render autocomplete options
**Current Implementation Notes:**
- Uses Alpine.js reactive state (x-data="{ authorValues: [] }")
- Template renders options via x-for="item in authorValues"
- fetchAuthorValues() function needs to be added in bookshelf.ts
- Other filters (genre, series, language) still need autocomplete support
**Limitations (To Be Addressed):**
- Still uses hx-trigger="change" (immediate filtering on blur)
- Should be changed to hx-trigger="keyup[key=='Enter']" (Enter key only)
- No search button added yet
- Only author filter has autocomplete (genre, series, language pending)
- Alpine.js state may conflict with native DOM manipulation in TypeScript
**Next Steps:**
- Add fetchAuthorValues() and fetchFieldValues() functions to bookshelf.ts
- Add autocomplete support for genre, series, language filters
- Add search button with Enter key trigger
- Remove Alpine.js wrappers if using native DOM approach
- Update all filter triggers from 'change' to 'keyup[key=="Enter"]'
**Migration Path:**
This is a transitional commit. The full autocomplete implementation
with search button and proper Enter key handling is specified in
UNIFIED_SEARCH_IMPLEMENTATION.md Phase 4.2-4.4.
