Implemented simple authentication for testing and admin panel for user management:
Backend:
- Add simple email/password login for test users (admin@test.local, user@test.local)
- Implement RBAC (Role-Based Access Control) with Permission enum
- Create admin endpoints for user management and system analytics
- Add bcrypt password hashing for test users
- Create script to generate test users in database
Frontend:
- Add SimpleLogin component for test authentication
- Create AdminPanel with user management and system analytics
- Add role-based navigation (Admin tab visible only for admins)
- Update AuthContext to support both MSAL and simple login
- Add API methods for admin operations
Features:
- Admins can view all users, manage roles, activate/deactivate accounts
- Admins can view system-wide analytics (users, conversations, tokens, costs)
- Regular users only see their own chats and usage
- Role badges in UI show user role (user/admin/superadmin)
Note: Simple authentication is for testing only. Production uses Azure AD MSAL.
