Add complete backend implementation for saved filters CRUD operations
with proper service layer architecture and RESTful API endpoints.
Service Layer (internal/services/filters.go):
- NewFiltersService() constructor following project patterns
- GetSavedFilters(): Retrieve all filters for user + resource type
- CreateSavedFilter(): Create filter with duplicate name validation
- UpdateSavedFilter(): Update filter with ownership verification
- DeleteSavedFilter(): Delete filter with user scoping
Business Logic:
- Filter name uniqueness enforced per user + resource type
- User ownership validation on all operations (JWT user_id)
- JSONB marshaling/unmarshaling for flexible filter storage
- Proper error wrapping with context messages
Handler Layer (internal/handlers/filters.go):
- NewFiltersHandler() constructor (receives db.Queries)
- GetSavedFilters: GET /api/saved-filters?resource_type=X
- CreateSavedFilter: POST /api/saved-filters
- UpdateSavedFilter: PUT /api/saved-filters/:id
- DeleteSavedFilter: DELETE /api/saved-filters/:id
Content Negotiation:
- Supports both JSON (API clients) and HTML (HTMX) responses
- wantsHTML() helper checks Accept header
- HX-Redirect header for HTMX form submissions
- Proper status codes (200, 201, 204, 400, 401, 404, 409)
Router Configuration:
- registerFiltersRoutes() function in internal/router/filters.go
- JWT middleware protection on all endpoints
- RESTful route structure: /api/saved-filters
- Registered in main router.go RegisterRoutes() function
- Added FiltersHandler to router.Config struct
Test Infrastructure:
- Added FiltersHandler to test server setup (test_helpers_test.go)
- FiltersHandler initialized in setupTestServer() function
- Router.Config includes FiltersHandler for integration tests
Code Quality:
- Follows PROJECT_GUIDELINES.md service layer patterns
- Uses database models (not custom domain models)
- JSONB returned as []byte (matches collections pattern)
- All errors wrapped with context using fmt.Errorf
- Handlers create services internally (not dependency injection)

Replace default CORS middleware with explicit CORS configuration in test
server setup to align with production security settings. This ensures test
environment matches production behavior and prevents potential CORS-related
test failures.
Changes:
- Replace echomiddleware.CORS() with echomiddleware.CORSWithConfig()
- Configure allowed origins, methods, and headers explicitly
- Set AllowCredentials to false for test environment
- Add ExposeHeaders for Content-Length
This maintains consistency with the CORS configuration applied to the main
server in commit fb05c49.
Rename test helper files from .go to _test.go suffix to comply with
Go testing conventions. This ensures proper test file recognition by
the Go toolchain and improves build organization.
- library_test_comprehensive.go → library_test_comprehensive_test.go
- test_helpers.go → test_helpers_test.go
- test_helpers_db.go → test_helpers_db_test.go
