fix(kiosk): force STREAM_MUSIC for TTS + JS feedback callbacks

Browse Source 
Android TTS was silently failing because engine.speak() used the default
audio stream, which may be muted while the media stream is not.

Changes:
- KioskActivity: speak() now passes Bundle with KEY_PARAM_STREAM=STREAM_MUSIC
  so TTS plays on the same channel as beep/media audio
- KioskActivity: add UtteranceProgressListener that calls window._kioskTtsDone()
  or window._kioskTtsError(uid, code) back into the WebView on completion/failure
- app.js testTTS(): kiosk path now shows real result from Android callbacks
  (success/error) with a 4s fallback timeout showing actionable troubleshooting hints
