HAKAN'S REQUIREMENT - Refactor API base URL configuration structure

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.
