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.

Integrate `navigation3` into `AppScreen` to manage tab transitions and
backstack state. Replaced manual tab state management with `NavDisplay`
and `NavBackStack`, and added horizontal slide animations for switching
between Home, Libraries, and Downloads screens.
Consolidates specific media selection callbacks (`onMovieSelected`, `onSeriesSelected`, `onEpisodeSelected`) into a single `onMediaSelected` handler that accepts a `MediaUiModel`. This simplifies the interface between the ViewModel and UI components across both mobile and TV screens, moving the type-checking logic into `AppViewModel`.
Adds the ability to play and pause media using the Center or Enter keys
without displaying the full player controls. When pausing via this
method, a brief visual "Pause" feedback overlay is shown in the center
of the screen.
- Added `TvPlayerHiddenStopFeedback` component and related logic
- Updated `handleTvPlayerRootKeyEvent` to support background playback toggling
- Added `pausePlayback` and `resumePlayback` to `PlayerViewModel` and `PlayerManager`
- Included comprehensive UI tests for the new hidden control behavior
Move the TV player queue into a simplified bottom inline playlist row and keep the existing seek bar -> controls -> playlist navigation hierarchy.
Focus playlist entry on the current queue item, keep focus pinned on the row at the horizontal edges, and return to the controls row on Up/Back.
Add compose coverage for playlist expansion, current-item focus, fallback focus, and row edge navigation.
