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 a validation pipeline using FluentValidation and
MediatR to enhance request validation. Added the following:
- Registered FluentValidation and MediatR dependencies in
`ReC.Application.csproj`.
- Updated `DependencyInjection.cs` to register validators
and MediatR behaviors, including `ValidationBehavior<,>`.
- Added `ValidationBehavior<TRequest, TResponse>` to handle
request validation in the MediatR pipeline.
- Created `ReadOutResQueryValidator` to enforce validation
rules for `ReadOutResQuery`.
- Refactored namespaces and imports for better organization.
These changes improve extensibility, maintainability, and
separation of concerns in the application.
