🔧 Hotfix: Production Deployment Authentication

This release fixes the authentication error in the production deployment workflow.

🐛 Issue Fixed

• Error: google-github-actions/auth failed with authentication requirements
• Root Cause: Production workflow was using Google Cloud auth while staging uses Firebase token

✅ Solution Applied

• Removed google-github-actions/auth@v2 step from production workflow
• Added Firebase token authentication to deployment commands
• Aligned production workflow authentication with working staging workflow pattern

🔄 Changes Made

• Updated deploy-prod.yml to use Firebase token authentication
• Matches the proven authentication method from deploy-staging.yml
• Eliminates Google Cloud service account dependency

🎯 Expected Result

• ✅ Production deployments should now authenticate successfully
• ✅ Firebase Functions deployment will work with token-based auth
• ✅ Consistent authentication pattern across staging and production

This hotfix ensures the revert to working state can deploy successfully to production.
