Refactor validation behavior and update result view command

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.
