Refine audio feedback and add AI intro speech for Forbidden Island

- Replace generic card/place SFX with thematic water sounds (splash, sink, raise, dry)
- Preload new water sound effects in PreloadScene
- Introduce AI character speech via SpeechQueue on character reveal
- Clear speech queue when advancing past character selection
