Added CreateResultViewCommandHandler to process creation of ResultView entities using IRepository<ResultView>. Also updated using directives to include necessary repository and entity namespaces.
Refactored ValidationBehavior to use C# 12 primary constructors and file-scoped namespaces, simplifying the Handle method logic. Updated CreateResultViewCommand to implement IAuthScoped and IRequest, replaced AddedWho with a non-serialized Scope property, and added necessary usings and namespace.
Introduced CreateResultViewCommand in the ReC.Application.ResultViews.Commands namespace. This class includes properties for ActionId, StatusCode, Header, Body, and AddedWho, and will be used as a command or DTO for creating ResultView entities.
