Added .env.example file with all AI service configuration placeholders.
Users should copy this to .env and fill in their actual API keys.
The .env file is already in .gitignore and will not be committed.
This allows users to configure Mistral, Vosk, and Coqui services without
committing sensitive API keys to git.

Updated docker-compose.yml to use hardcoded Mistral API key from development
configuration instead of relying on environment variable.
This fixes the 500 error (which was masking a 401 from Mistral due to missing API key).

PROBLEM:
- /admin redirects to / (home page)
- Admin pages were wrapping themselves in <AdminLayout>
- This caused double-nested layout (header, nav, footer twice)
ROOT CAUSE:
Admin pages (AdminDashboardPage, AdminUsersPage, etc.) were individually wrapping
their content in <AdminLayout> component. But the App.tsx routing already renders
<AdminLayout> as the parent element for all /admin routes, and AdminLayout uses
<Outlet /> to render child routes.
This created a nested structure:
AppLayout -> AdminLayout (from routing) -> AdminLayout (from page) -> Page Content
SOLUTION:
- Removed <AdminLayout> wrappers from all admin pages
- AdminLayout now always uses <Outlet /> instead of {children || <Outlet />}
- Removed unused 'children' parameter from AdminLayout
- Admin pages now render directly in the Outlet of AdminLayout
CHANGES:
- AdminDashboardPage.tsx: Removed AdminLayout import and all <AdminLayout> tags
- AdminUsersPage.tsx: Removed AdminLayout import and all <AdminLayout> tags
- AdminUserDetailPage.tsx: Removed AdminLayout import and all <AdminLayout> tags
- AdminReportsPage.tsx: Removed AdminLayout import and all <AdminLayout> tags
- AdminStoryGeneratorPage.tsx: Removed AdminLayout import and all <AdminLayout> tags
- AdminLayout.tsx: Removed unused children parameter, always use <Outlet />
Now /admin will correctly render the AdminLayout with nested admin pages.

PROBLEM:
- Login returns JWT token with 'sub' claim
- /me endpoint tries to read user ID from JWT
- Gets 401 Unauthorized because user ID claim cannot be found
ROOT CAUSE:
ASP.NET Core JWT middleware automatically maps JWT standard claims to .NET claim types:
- JwtRegisteredClaimNames.Sub ('sub') -> ClaimTypes.NameIdentifier ('http://schemas.xmlsoap.org/ws/2005/05/identity/claims/nameidentifier')
Controllers were looking for 'sub' or 'nameid' but JWT middleware creates the claim with the full URI.
SOLUTION:
Updated all controllers to use ClaimTypes.NameIdentifier with fallback to 'sub':
- AuthController.GetCurrentUser()
- AdminController.DeleteUserAsync()
- StoryController.GetUserId()
This ensures the user ID can be found regardless of how the JWT middleware maps the claims.
CHANGES:
- AuthService: Generates JWT tokens with JwtRegisteredClaimNames.Sub (JWT standard)
- AuthController: Uses ClaimTypes.NameIdentifier ?? 'sub' fallback
- AdminController: Uses ClaimTypes.NameIdentifier ?? 'sub' fallback
- StoryController: Uses ClaimTypes.NameIdentifier ?? 'sub' fallback
- LessonsEndpoints.cs: Added .RequireAuthorization() to all GET endpoints
- docs/features/admin-module.md: Updated acceptance criteria and requirements
- Added unit tests in JwtTokenValidationTests.cs to verify the fix

- 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.

- 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
