- Fixed BaseAddress setup in MistralConnector to work without API key
- Reverted seed data to use hardcoded bcrypt hashes (compatible with PasswordHasher)

ef72cbea18 fix(backend/auth): Fix JWT token claim mapping for user ID
- Changed AuthService.GenerateJwtToken to use JWT standard claims:
  - JwtRegisteredClaimNames.Sub for user ID (instead of ClaimTypes.NameIdentifier)
  - JwtRegisteredClaimNames.Name for username
  - JwtRegisteredClaimNames.Email for email
  - JwtRegisteredClaimNames.UniqueName for additional username claim
  - Kept ClaimTypes.Role for role

- Updated AuthController.GetCurrentUser to use JwtRegisteredClaimNames.Sub
- Updated AdminController.DeleteUserAsync to use JwtRegisteredClaimNames.Sub

This fixes the 401 error when calling /me after login. The issue was that
tokens were being generated with ClaimTypes.NameIdentifier claim, but the
JWT middleware doesn't automatically map this to a claim that can be found
with User.FindFirst(). Using standard JWT claims (sub, name, email) ensures
proper compatibility with ASP.NET Core's JWT authentication.

42778ec34b fix(backend/auth): Fix authentication bugs
- 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
