Added `[Obsolete("Use MediatR")]` attributes to various controller and service classes to indicate deprecation in favor of MediatR. Simplified generic type constraints in `CRUDControllerBase` and related files by removing `IUnique<TId>`. Improved structure and documentation in `CSPMiddleware.cs`. Introduced new extension methods in `EntityExtensions.cs` for safer retrieval of 'Id' properties. Removed `IUnique.cs` interface and updated project dependencies in `DigitalData.Core.Application.csproj` for caching. Overall, these changes enhance code maintainability and clarity.
