Enhance inline and admin statistics features

- Updated inline user statistics message to provide clearer information about bot usage and user status.
- Refactored system statistics retrieval to utilize the PanelApiService for improved data accuracy and detail, including memory usage and bandwidth statistics.
- Simplified the success message for bulk promo code creation by removing the codes list from the message, ensuring clarity.
- Enhanced localization files to reflect changes in success messages and added new labels for better user experience.
