Home screen, library-wide search, splash with orbital particles, macOS download fix

- Add Netflix-style Home with recent audiobooks/podcasts, list/grid toggle shared with Library
- Add searchable libraries — audiobooks filter on title/author; podcasts also index and search episodes across the whole library
- Add unified context menu (download / progress remove) across Home, Library, and PodcastDetail
- Rework cover badges: listened checkmark top-right, download indicator bottom-right; hide progress bar when finished
- Add AirPlay picker in PlayerBar
- Replace splash with four-phase animation: orbital particles → attract → flash → fade; cross-platform iOS+macOS, runtime AppIcon lookup
- Fix macOS parallel downloads: align connection settings with iOS, raise timeoutIntervalForRequest to 300s
- Fix progress deletion using server-side progress UUID (DELETE /api/me/progress/:id)
- Bump CFBundleVersion to 8
