Refactors the TV navigation drawer to use specific library routes instead
of a static libraries overview. Added a `NavDisplay` with a backstack to
manage navigation between the Home screen and individual Library screens
directly from the drawer.
- Replace `TvDrawerDestination` enum with `Route` in the navigation drawer
- Dynamically populate drawer items based on available libraries
- Add `NavDisplay` to `TvAppScreen` for nested TV navigation
- Connect `TvLibraryScreen` to `AppViewModel` for media selection handling
- Remove back button from `TvLibraryScreen` in favor of drawer navigation
- Update `TvNavigationDrawerTest` to reflect routing changes
Temporarily hide cast rows on TV movie, episode, and series detail surfaces while preserving the surrounding section layout.
Simplify TV player queue rows by removing the secondary subtitle line so queued items scan more cleanly.
Increase the next-up queue fetch from 5 to 10 items and skip missing playlist episodes with an error log instead of throwing during queue mapping.
Move playback-related media state into shared model types and make the player consume a single PlayableMedia object instead of separately loading MediaItems, track preferences, resume positions, and media segments.
This updates PlayableMediaRepository to return playable media bundles, seeds the player playlist with the current item, keeps next-up entries in the same model, restores resume/segment handling, and fixes current queue highlighting.
The change also moves track preference models into core-model, centralizes Jellyfin BaseItemDto conversion, removes placeholder movie audio/subtitle fields, bumps the offline Room schema, and updates mobile/TV queue UI code for the playlist model.
