Introduce generic IRepository<T> and refactor repositories

Added a generic IRepository<T> interface for common CRUD operations and updated ICatalogRepository to inherit from it, removing redundant methods. Updated CatalogRepository to implement the new interface. Cleaned up DbFirst.Domain.csproj by removing an unused folder reference. These changes improve code reuse and align with clean architecture practices.
