feat: Optimized media output panel availability checks

Adjusted media output panel availability check logic based on Android version.

- For Android 14 and above, assume the panel is always available.
- For Android 12 and 13, check if the system UI can handle the media output dialog intent.
- For Android 11 and below, check if the Settings app can handle the media output panel intent.

If the panel is unavailable, hide the media control buttons.
