Added the `MediatR` NuGet package (v13.1.0) to enable the mediator pattern. Updated `ReC.Application.csproj` to include a project reference to `ReC.Domain`.
Introduced `RecActionDto` as a Data Transfer Object (DTO) for representing "RecAction" details, including properties for endpoints, authentication, and SQL connections.
Added `ReadRecActionQuery` to handle queries for retrieving `RecActionDto` objects, leveraging MediatR. This query filters results based on `ProfileId`.
