Impossible to login using google account

### Custom Node Testing

- [x] I have tried disabling custom nodes and the issue persists (see [how to disable custom nodes](https://docs.comfy.org/troubleshooting/custom-node-issues#step-1%3A-test-with-all-custom-nodes-disabled) if you need help)

### Expected Behavior

Option to login with google account.

### Actual Behavior

It is now impossible to login using google account. The only option that is presented is github.

### Steps to Reproduce

Visit cloud.comfy.org
Try to login

### Debug Logs

```powershell
Nope.
```

### Other

_No response_

Start by reproducing the sign-in flow at cloud.comfy.org and compare the available providers with the expected Google option. Trace the authentication entry point in the repository, then verify that Google login is presented and completes successfully alongside GitHub login.
