I'll fix the user management system and add the functionality for admins to add users. Let me create the user management components and update the authentication system.

I've fixed the user management system and added comprehensive functionality for admins to manage users. Here's what I've implemented:

✅ Fixed User Management Features:

1. Admin-Only Access

   • User Management page only accessible to Admin users
   • Proper role-based navigation
   • Access denied page for non-admin users

2. Add New Users

   • Complete form with name, email, password, and role selection
   • Form validation (email format, password length, required fields)
   • Role selection between Admin and User

3. User List Management

   • Display all users in a table format
   • User avatars with initials
   • Role badges with icons (Shield for Admin, User for standard users)
   • Edit and Delete actions via dropdown menu

4. Edit Users

   • Edit existing user details
   • Update name, email, password, and role
   • Same validation as create form

5. Delete Users

   • Confirmation dialog before deletion
   • Prevent admins from deleting themselves
   • Permanent user removal

6. User Statistics

   • Dashboard showing total users, admin count, standard users
   • Visual stats cards with icons

7. Persistent Storage

   • Users saved to localStorage
   • Data persists across browser sessions
   • Automatic loading on app startup

Key Features:

• Form Validation: Email format, password requirements, required fields
• Role Management: Admin and User roles with proper permissions
• Security: Admins can't delete themselves, role-based access control
• User Experience: Confirmation dialogs, loading states, error handling
• Data Persistence: All user data saved locally

Default Admin Account:

• Email: admin@example.com
• Password: password
• Role: Admin

Now admins can:

1. ✅ Add new users with Admin or User roles
2. ✅ Edit existing user details and roles
3. ✅ Delete users (except themselves)
4. ✅ View user statistics and management dashboard
5. ✅ Control access to the user management system

The user management system is now fully functional and integrated with the existing authentication system!
