Refactor API clients to use primary constructor for HttpClient

Refactored CatalogApiClient, DashboardApiClient, LayoutApiClient, and MassDataApiClient to use C# primary constructor syntax for injecting HttpClient. Removed private _httpClient fields and updated all usages to reference the constructor parameter directly. This change simplifies the code and modernizes dependency injection without altering any API logic.
