fix: Refactors casting player and components

Refactors the casting player screen and related components for improved code clarity, performance, and maintainability.

- Removes unused code and simplifies logic, especially around audio track selection and recommended stereo track handling.
- Improves the formatting of trickplay time displays for consistency.
- Streamlines UI elements and removes unnecessary conditional checks.
- Updates the Chromecast component to use hooks for side effects, ensuring the Chromecast session remains active.
- Improves the display of the language in the audio track display.
