fix: Remove --prebuilt flag and improve health checks

- Remove --prebuilt flag from both staging and production deployments
- Let Vercel handle the build process during deployment (simpler approach)
- Update health checks to test actual deployment URLs first
- Add fallback to test production/staging domains if deployment URL fails
- This resolves the prebuilt environment mismatch and health check failures
