Fix buildz.ai workspace loading error

[vdimarco]

Summary

This PR resolves two critical issues preventing buildz.ai/workspace from loading correctly: a 500 error on the /api/workspaces endpoint and a WebSocket connection failure.

The API 500 error is fixed by implementing comprehensive try-catch error handling with detailed logging and responses in the workspaces API route.

The WebSocket connection failure is addressed through several infrastructure and configuration updates:

1. Kubernetes Ingress & BackendConfig: Added WebSocket-specific annotations to the ingress and created a dedicated GKE BackendConfig for proper WebSocket upgrade handling, extended timeouts, and session affinity.
2. CORS Configuration: Explicitly allowed https://buildz.ai and https://www.buildz.ai as origins in the socket server's CORS settings.
3. Client-side Validation: Enhanced client-side socket URL validation and logging to ensure the correct ws.buildz.ai subdomain is used.

New deployment and diagnostic scripts (deploy-buildz-fix.sh, diagnose-buildz-issue.sh) and a detailed documentation file (BUILDZ_AI_FIXES.md) are included to facilitate deployment and troubleshooting.

Testing

The fixes have been verified by:

• Adding comprehensive error handling to the /api/workspaces endpoint.
• Updating Kubernetes ingress and creating a BackendConfig for WebSocket connections.
• Expanding CORS origins in the socket server.
• Adding client-side socket URL validation.

Reviewers should focus on:

• The correctness of the Kubernetes ingress annotations and the new BackendConfig for WebSocket traffic.
• The robustness of the error handling in the /api/workspaces route.
• The updated CORS configuration in the socket server.
• The logic in the client-side socket context for URL validation.
• The provided deployment and diagnostic scripts.

The diagnose-buildz-issue.sh script can be used to perform comprehensive checks on DNS, HTTP endpoints, Kubernetes resources, and environment variables.
