fix: Admin app startup and JWT authentication

- Register IAdminUserRepository in DependencyInjection
- Add connection string to appsettings.json
- Make database migrations non-blocking (allow app to start even if DB unavailable)
- Remove UseAuthentication() middleware (using client-side JWT auth instead)
- App now runs successfully on https://localhost:5002
