Enhance promo code management and user statistics features

- Introduced a unified promo code management system, allowing admins to view and manage both active and inactive promo codes with detailed information.
- Updated the promo code detail view to include status indicators and management options for editing, toggling status, and viewing activation history.
- Enhanced user statistics display by restructuring the information layout and adding new labels for clarity.
- Improved localization files to support new messages and labels related to promo code management and user statistics.
- Implemented error handling for suspicious promo code attempts, integrating a notification system for better admin awareness.
