implement season selection logic and update SeriesScreen UI

- Update `SeasonTabs` to handle selection state and provide an `onSelect` callback.
- Implement `selectedSeason` state in `SeriesScreen` using `remember` and `mutableStateOf`.
- Refactor `SeriesScreen` to display episodes based on the currently selected season.
- Adjust spacing and remove redundant styling from `EpisodeCarousel` items.
- Clean up unused imports and commented-out code in `SeriesComponents.kt`.
