feat: Replace individual action icons with dropdown menu in users table

Improved UX by consolidating user actions into a single dropdown menu:
- Added MoreVert icon button to open actions menu
- Menu includes: View Details, Edit User, Activate/Deactivate, Delete User
- Delete action shown in error color for visual distinction
- Cleaner table layout with single action button per row
