IInsertProcedure now inherits from IRequest<long> to integrate with MediatR's request/response pattern. Removed the ToObjectProcedure method and added the necessary MediatR using directive.
Changed IInsertProcedure.ToObjectProcedure to accept an optional addedWho parameter. Introduced InsertObjectProcedureExtensions with an ExecuteInsertProcedure extension for ISender, defaulting addedWho to "Rec.API" if not specified.
Updated IInsertProcedure and all implementations to accept an optional 'addedWho' parameter in ToObjectProcedure, defaulting to "Rec.API". This enables tracking of the entity responsible for insert operations.
Refactored insert procedure-related classes by moving each record type (Action, Endpoint, EndpointAuth, Profile, Result, EndpointParams) and the IInsertProcedure interface into their own files under the new InsertProcedure namespace. Updated InsertObjectProcedureValidator to use the new namespace. This improves code organization, readability, and maintainability.
