Add robust lifecycle management for `audio_player` service in system routes

- Implement `stop` and `resume` functionality for `audio_player` with timeout handling.
- Add readiness checks and informative logging to ensure service stability during start and stop operations.
- Allow system continuation even if `audio_player` encounters errors or is unavailable.
