update MediaHero heights and refactor SeriesHero

- Increase `MediaHero` height from 200dp to 300dp in `EpisodeScreen` and `MovieScreen`.
- Replace `SeriesHero` with `MediaHero` in `SeriesScreen` and increase height to 350dp.
- Remove redundant `SeriesHero` component from `SeriesComponents.kt`.
- Update `SeriesViewModel` to use `ImageType.PRIMARY` for the hero image URL.
- Remove comments from `MediaHero.kt`.
