Make ambient music react to wild mode

- When wild mode turns on, automatically start ambient playback using the
  theme's wild ambient variant, even if normal ambience was off.
- Track wild-forced ambient starts via _snonuxAmbientWildForced so that
  deactivation can fade to silence when the user never opted in, or
  crossfade back to normal when they did.
- Do not persist forced-wild playback as a normal ambient preference;
  only user toggles (p key / ambient button) are saved.
- Enhance wild ambient playback: denser pulses (1.5x bpm), increased noise
  texture, slightly raised gain (capped at 0.15), and deeper lowpass filter
  sweeps on pulses.
- Re-sync FX button states after ambient start/stop so the ambient button
  accurately reflects the current state.
