Introduce a `IS_DEBUG_ENABLED` boolean flag in `BuildConfig` for both
debug and release build types. This flag is used to suppress update
notifications in `PlayerFragment` when debugging and before its a version released.
- Implement `seekToNext` and `seekToPrevious` in `PlayerService` to allow switching between radio stations.
- Update `compileSdk` and `targetSdk` to 37 and bump version to 14.6.
- Modify `PlayerService` to remain active while paused to improve playback resumption.
- Modernize media resumption logic using Media3 `isRecent` check instead of legacy extras.
- Refactor `DefaultRenderersFactory` to use non-nullable `AudioSink` return types.
- General code cleanup using KTX extensions (e.g., `View.isEmpty()`) and Kotlin property access syntax.
