feat: add :app-tv module as Android TV starting point

Creates a new :app-tv application module that reuses shared business
logic from :core:model, :core:data, :core:player, and :feature:shared,
with its own TV-specific UI layer.

- TvApplication + TvActivity with full Hilt + Navigation3 wiring
- TvHomePage reusing HomePageViewModel from :feature:shared
- Copied common UI components (PosterCard, WaitingScreen, etc.)
- Copied login screen and form components
- TV navigation module with Home + Login route entry builders
- Material3 theme copied from mobile (ready for TV customization)
- AndroidManifest with LAUNCHER + LEANBACK_LAUNCHER intent filters
- Excludes :feature:download (downloads are mobile-only)
