fix: google anti-bot flag + persistent/safe settings apply + TTS engine wiring

- Chrome: --disable-blink-features=AutomationControlled (+ ko-KR) so Google
  shows results, not the /sorry/ automation block.
- Settings persist to /data/jarvis-settings.json (survives recreate; entrypoint
  re-merges it) AND the runtime config; apply restarts via a DETACHED process so
  the HTTP response isn't dropped when the bridge restarts.
- Bridge reads tts_engine from the settings config so the TTS-engine choice
  actually applies.
