- Fix case-insensitive email lookups in AuthService (RegisterAsync, LoginAsync, CreateAdminUserAsync)
- Fix User.Create factory method to explicitly set Role property (C# object initializer behavior)
- Assign Admin role to seeded admin user in SeedDataExtension
- Add [AllowAnonymous] to Register and Login endpoints in AuthController (defensive programming)
- Increase JWT ClockSkew to 5 minutes for clock difference tolerance
These fixes resolve issues where:
- Login fails with 401 due to case-sensitive email comparison
- User role is null instead of 'User' or 'Admin'
- JWT token validation too strict on clock synchronization
