Add configurable background music per level with song selector in the
level editor General tab. Update ship model, add base3 model, add
song2/song3 audio tracks, and clean up level config formatting.

Root cause: The old Sound API (new Sound()) is incompatible with
AudioEngineV2 in BabylonJS 8.32.0, causing silent failures where the
explosion.mp3 file was never fetched from the network.
Audio System Fixes:
- Migrate explosion sound from Sound class to AudioEngineV2.createSoundAsync()
- Use StaticSound with spatial property instead of old Sound API
- Configure audio engine with listenerEnabled and listenerAutoUpdate
- Attach audio listener to camera for proper 3D positioning
Spatial Audio Implementation:
- Use spatialEnabled: true with spatial-prefixed properties
- Attach sound to explosion node using sound.spatial.attach()
- Properly detach and cleanup after explosion finishes (850ms)
- Configure exponential distance model with 500 unit max distance
Technical Changes:
- Replace new Sound() with await audioEngine.createSoundAsync()
- Change _explosionSound type from Sound to StaticSound
- Update imports: Sound → StaticSound
- Use sound.spatial.attach(node) instead of attachToMesh()
- Use sound.spatial.detach() for cleanup
- Remove incompatible getVolume() calls
Audio Engine Configuration:
- Add CreateAudioEngineAsync options for spatial audio support
- Attach listener to camera after unlock in both level flows
- Enable listener auto-update for VR camera movement tracking
This fixes the explosion sound loading and enables proper 3D spatial
audio with distance attenuation.
