Feature/music skip delay (#115)

* feat: Add configurable delay for music module skip when nothing playing

- Add 'skip_when_nothing_playing' and 'skip_delay_seconds' config options
- Implement timer-based skip logic that waits 2 seconds before skipping
- Reset timer when music resumes or display is deactivated
- Improve user experience by preventing jarring immediate skips
- Maintains backward compatibility with existing configurations

* feat: Add live priority support to music manager

- Add 'live_priority' and 'live_game_duration' config options for music
- Integrate music manager into live priority rotation system
- Add 'music_live' mode that participates in live priority takeover
- Music manager joins live priority rotation when actively playing
- Supports future plugin ecosystem with consistent live priority interface
- Maintains backward compatibility with existing music configurations

* feat: Add new music settings to web interface

- Add 'Skip When Nothing Playing' checkbox and delay configuration
- Add 'Enable Live Priority' checkbox and duration configuration
- Update music form JavaScript to save all new settings
- Users can now configure music skip behavior and live priority through web UI

* fix: Improve music live priority integration

- Enhanced music live content detection with detailed logging
- Modified live priority logic to properly handle music mode
- Added music to live priority sports collection when actively playing
- Updated live priority rotation to handle music mode correctly
- Improved live priority takeover logic for music manager
- Music now properly participates in live priority rotation when playing

* perf: Reduce logging frequency for music live priority

- Add timestamp-based throttling to music live priority logging
- Info messages now only appear every 30 seconds instead of every few milliseconds
- Debug messages are also throttled to reduce log spam
- Maintains visibility of important events while reducing noise

* Fix unreachable code bug in music live priority handling

- Moved music live priority logic outside the sports iteration loop where it was unreachable
- The 'if sport == music' block was never executed since 'music' wasn't in the sports list
- Consolidated music handling in its own separate section for cleaner code structure
- Added music configuration options to config template
- Maintained exact same functionality while eliminating dead code

* Fix music_live_game_duration setting not being used

- Modified get_current_duration() method to check for music live priority mode
- When music is in live priority mode, use configured live_game_duration setting
- Added proper config reading for music_live_game_duration during initialization
- Ensures music displays for the configured duration when in live priority mode

* Fix stale timestamp bug in live priority debug logging

- Fixed issue where debug log at line 1240 was using a stale current_time variable
- The current_time variable was conditionally reassigned in music live priority check
- This caused inconsistent log throttling behavior
- Now uses fresh current_time_for_debug variable for accurate throttling
