Enhance user data handling in users page

- Added a new API call to fetch unique IPs alongside existing user data, improving the richness of information displayed.
- Implemented derived state to organize unique IPs by user, allowing for better data presentation in the UI.
- Updated the table to display IP-server pairs for each user, enhancing clarity and usability.
- Improved error handling during data fetching to ensure robust user experience.
