Replaced ApiBaseUrl and DataApiBaseUrl with BaseUrl, ApiDefaultUrl, and service-specific configuration sections (AuthService, UserManagerService, DbFirstService). Updated AppSettings and all code references to use the new structure. Revised logic for HTTP client base URL selection to prefer service-specific settings. Updated appsettings files and added an example configuration for clarity and maintainability.
- Introduced AuthService, IAuthApiClient, and AuthApiClient for managing authentication state and API calls (login, logout, session restore).
- Added Login.razor and LoginLayout.razor for the login page, including styling and logic.
- MainLayout.razor now checks authentication on load, restores sessions from sessionStorage, and redirects to /login if unauthenticated. Displays username and logout button when logged in.
- Implemented JS interop (authStorage) for persisting authentication info in sessionStorage.
- Registered AuthService, CookieContainer, and API clients in Program.cs to share cookies and support authentication.
- Updated AppSettings and appsettings files to support separate ApiBaseUrl and DataApiBaseUrl.
- Minor CSS improvements for username display in the top bar.
Replaced direct IConfiguration usage with a strongly-typed AppSettings class for accessing the API base URL. Registered AppSettings with DI and updated Dashboard.razor to use IOptions<AppSettings>. Updated using statements and DI setup for improved type safety and centralized configuration management.
