Rewrite /api/media-items/search endpoint to detect HTMX requests and return appropriate response format. The endpoint now checks for HX-Request header and routes to HTML renderer or JSON handler accordingly.
- Check HX-Request header to detect HTMX requests
- Return HTML via BooksGrid template for HTMX requests
- Return JSON for API clients (existing behavior)
- Add handleSearchHTML function for HTML rendering
- Use shared MediaHandler.ExecuteSearch method
- Eliminates previous issue where JSON was rendered in browser
- Update Config struct to replace EbookHandler with MediaHandler, SearchHandler, MatchingHandler
- Add CollectionHandler to Config struct
- Update RegisterRoutes to call new registration functions
- Create registerCollectionsRoutes for 15 collection endpoints
- Create registerSearchRoutes for search endpoints (uses MediaHandler.SearchMediaItems, MatchingHandler.QueryBooks)
- Create registerMatchingRoutes for 8 matching/linking endpoints
- Update registerMediaRoutes to use cfg.MediaHandler (adds 24 media endpoints)
- Create registerProgressRoutes for 3 universal progress endpoints
All 57 routes preserved and properly registered with correct handlers.
No functionality lost, all endpoints work identically.
This is Phase 5 of the ebook.go refactoring plan.
