🐛 Handle GA script load failure to prevent bot from hanging (#2446)

## Summary
- Add `script.onerror` handler in `initGoogleAnalytics` so the promise
resolves even when the GA script fails to load (ad blockers, network
errors), preventing the bot from hanging indefinitely.
- Bump `@typebot.io/js` and `@typebot.io/react` versions to `0.10.2`.

## Test plan
- [ ] Enable a Google Analytics integration block in a bot
- [ ] Block `googletagmanager.com` (e.g. via ad blocker) and verify the
bot still loads
- [ ] Check that `"Failed to load Google Analytics script"` appears in
the console
