fix(websocket): harden dispatch and drop provider-level router hook

Address CodeRabbit review on the pub/sub provider:

- Wrap each subscriber call in dispatchMessage with try/catch so one
  throwing handler can't abort the rest of the fan-out, nor get
  misreported as a parse failure by the outer onmessage catch.
- Replace the provider-level useAppRouter() hook with expo-router's
  static router for the Play command, per the repo guideline
  (useRouter at provider level can trigger tab switches). The Play
  navigation hardcodes offline:"false", so the offline-aware wrapper
  added nothing here.
