Migrate to AudioEngineV2 and fix Meta Quest 2 controller detection

Browse Source 
- Upgrade audio system from deprecated Sound API to AudioEngineV2
  - Use CreateAudioEngineAsync() for audio engine initialization
  - Replace new Sound() with createSoundAsync() throughout codebase
  - Track sound playing state manually (StaticSound lacks isPlaying)
  - Use volume property instead of setVolume() method
  - Use stop() instead of pause() for proper StaticSound lifecycle

- Fix controller detection for Meta Quest 2
  - Check for already-connected controllers after entering XR mode
  - Fixes issue where Quest 2 controllers only become available after enterXRAsync()
  - Maintains backward compatibility with WebXR emulator

- Improve initialization performance
  - Move RockFactory.init() to main initialization (before level select)
  - Pre-load asteroid meshes and explosion particle systems on startup
  - Level initialization now only creates asteroids, not resources

- Refactor level initialization flow
  - Level creation now happens before entering XR mode
  - Add level ready observable to track initialization completion
  - Show loading messages during asteroid creation
  - Extract loading message logic to separate module

- Add audio unlock on user interaction (button click)
- Make play() methods async to support AudioEngineV2
- Pass AudioEngineV2 instance to Ship and Level1 constructors
