feat: Enhances casting player with API data

Enriches the casting player screen by fetching item details from the Jellyfin API for a more reliable and complete user experience.

The casting player now prioritizes item data fetched directly from the API, providing richer metadata and ensuring accurate information display.

- Fetches full item data based on content ID.
- Uses fetched data as the primary source of item information, falling back to customData or minimal info if unavailable.
- Improves UI by showing connection quality and bitrate.
- Enhances episode list display and scrolling.
- Adds a stop casting button.
- Minor UI adjustments for better readability and aesthetics.

This change enhances the accuracy and reliability of displayed information, improving the overall user experience of the casting player.
