- Added 'enabled' property to FunConfigSchema with a default value of true for better configuration management.
- Refactored getFunConfig to return a complete default configuration when no data is found.
- Improved globals.css by expanding CSS variables for light and dark themes, enhancing styling consistency across the application.
