This commit introduces the `[ApiExplorerSettings(IgnoreApi = true)]` attribute to various DTO classes to exclude them from API documentation. The `using Microsoft.AspNetCore.Mvc;` directive has been added to several files to support ASP.NET Core MVC features.
Additionally, comments in `HistoryController.cs` have been reformatted for clarity, and `LocalizationController.cs` has been updated with standard API controller attributes. These changes improve code organization and maintain cleaner API documentation.
- Core-Bibliotheken und `UserManager.Infrastructure` in der Application-Schicht auf Version 2.0.0.0 erhöht.
- DbSet-Eigenschaften aus dem DbContext injiziert.
