- Updated the logic for retrieving unique users today to ensure only the latest records are considered, improving accuracy in user engagement metrics.
- Enhanced the command table to display user age alongside their name and login count, providing more comprehensive insights into user demographics.

These changes collectively improve the reporting of user statistics and enhance the clarity of the displayed data.
