feat: Enhance user management with multi-select, filters, validation, and UI improvements

- Implemented multi-user selection and deletion with confirmation.
- Added filter buttons (All, Not Active, Enable, Disable) with client-side logic.
- Fixed "Select All" checkbox to only affect visible users after filtering.
- Implemented real-time username validation (alphanumeric only).
- Added a disable to prevent submit validation error
- Ensured that select all deselect button, work with filters and sorting
- Improve UI to be more intuitive.
-Improved responsivity buttons in smaller devices
