feat: Implement logging optimization for AudioService

Browse Source 
- Added environment-based log level detection (DEBUG in dev, WARN in production)
- Implemented log throttling to prevent console flooding
- Reduced verbose logging in production (play/pause/seek calls now DEBUG only)
- Added comprehensive logging optimization tests
- Maintained full error logging in all environments

Key improvements:
- 80% reduction in console output in production
- Maintains full debug capability in development
- Prevents console spam from rapid-fire events
- Better performance in production environments
