Continue to work through 429/500s.

- The root of this issue was actually a genai SDK bug that was fixed here: https://critique.corp.google.com/cl/753255997
- Upgrade to latest genai SDK for latest bug fixes (including the above)
- Removed specific 429 handling for uncaught rejections.

Fixes https://b.corp.google.com/issues/413760164
