✅ Role Management – Assign roles to control user access levels
✅ User List View – Display users in a tabular format with ID, name, email, and role
✅ Search & Filter – Find users easily with a search function
✅ Responsive UI – Clean and mobile-friendly interface using Bootstrap
✅ Database Integration – Uses MySQL for storing user information
