Fix: Improves Chromecast casting experience

Fixes several issues and improves the overall Chromecast casting experience:

- Implements an AbortController for fetching item data to prevent race conditions.
- Syncs live progress in the mini player more accurately using elapsed real time.
- Prevents event propagation in the mini player's play/pause button.
- Ensures the disconnect callback in the connection menu is always called.
- Retries scrolling in the episode list on failure.
- Handles unmute failures gracefully in volume controls.
- Clamps seek positions to prevent exceeding duration.
- Fixes reporting playback start multiple times
- Improves segment calculation in `useChromecastSegments`
- Prevents race condition with `isPlaying` state in `Controls` component

Also includes minor UI and timing adjustments for a smoother user experience.
