Refactor DeleteEndpointAuthProcedure to use MediatR handler

Refactored DeleteEndpointAuthProcedure by removing the ToObjectProcedure method and introducing DeleteEndpointAuthProcedureHandler, which implements IRequestHandler and delegates deletion via MediatR's ISender. Consolidated using directives and namespace declarations.
