Update IUpdateProcedure to use MediatR IRequest<int>

Refactored IUpdateProcedure to inherit from MediatR's IRequest<int> for integration with the MediatR pipeline. Removed the ToObjectProcedure method and added the necessary using directive for MediatR. This simplifies the interface and standardizes request handling.
