Refactor DeleteActionProcedure to use MediatR handler

Refactored DeleteActionProcedure to implement IDeleteProcedure directly and removed the ToObjectProcedure method. Introduced DeleteActionProcedureHandler using MediatR's IRequestHandler to delegate deletion logic via ISender. Updated using directives for MediatR integration.
