Add debugging tools and optimize auth endpoints

🔧 Debugging Improvements:
- Optimize setup-auth endpoint to avoid timeouts
- Add table existence checks before operations
- Simplify permission system for faster setup
- Add environment variable validation
- Create test-db endpoint for connection debugging

🚀 Performance Optimizations:
- Break down large SQL queries into smaller chunks
- Add early returns for already-setup scenarios
- Reduce permission complexity during initial setup
- Better error messages for troubleshooting

🧪 New Debug Endpoints:
- /api/test-db - Test database connectivity
- /api/setup-auth - Optimized schema setup

These changes should resolve timeout issues and provide better debugging information for authentication problems.
