Introduced `UserPreferencesDto` to represent UI preferences, including theme, dark mode, and grid layouts. Added the `IUserPreferencesService` interface and implemented it in `UserPreferencesService` to manage preferences stored in the distributed cache (`dbo.TBDD_CACHE`). Registered `UserPreferencesService` in dependency injection and added a NuGet reference for `Microsoft.Extensions.Caching.Abstractions`. Created `UserPreferencesController` with `GET` and `PUT` endpoints to retrieve and save user preferences. Validated theme names in the `PUT` endpoint. Updated `Program.cs` to ensure proper service registration.
