Make sound support optional and guard against missing audio dependencies

- Move simpleaudio to optional dependency (audio extra)
- Add DummySound fallback when optional audio libs are unavailable
- Import simpleaudio/numpy lazily with ImportError handling
- Remove Docker-specific sound disabling logic
- Improve typing and robustness of sound utilities
