implement episode details screen and ViewModel

- Create `EpisodeScreen` and `EpisodeCard` components with adaptive layouts for wide and narrow viewports.
- Implement `EpisodeScreenViewModel` to fetch "Next Up" episode data using the Jellyfin API.
- Add `EpisodeUiModel` and `CastMember` data classes for content representation.
- Develop custom UI components including `EpisodeHero`, `PlaybackSettings`, `CastRow`, and `EpisodeTopBar`.
- Define a dedicated color palette for the episode view in `EpisodeColors.kt`.
- Integrate navigation to the player activity from the play buttons.
