alexsong-oai 6fe77fc123 Add experimental GCP account setup to the app server (#57394) ...

## What changed

- Add `account/gcp/setup` to configure the built-in Vertex AI provider with a project, optional location (defaulting to `global`), and optional credential file. Omitting the file clears the active user override and uses Application Default Credentials.
- Validate configuration and obtain an access token before saving, return structured credential failure reasons, and reload the model catalog on the next `model/list` request.
- Share configuration previews and version-checked writes with Bedrock setup to reject conflicting settings and concurrent configuration changes.

## Testing

Add tests for credential selection and ADC fallback, catalog refresh, invalid credentials, policy and endpoint conflicts, cancellation when network permission is revoked, and configuration version conflicts.
