Introduced the `InvokeRecActionQuery` class in the `ReC.Application.RecActions.Commands` namespace to implement the Mediator pattern using the MediatR library.
- Added `using MediatR;` directive to include the library.
- Implemented `IRequest` interface in the new class.
- Added `ProfileId` property with `init` accessor for immutability.
- Organized the code under a new namespace for better structure.
