The Mem0 API rejects an add with no entity ID ("At least one entity ID is
required: user_id, agent_id, app_id, or run_id"), but Add Memory marked
user_id optional, so Zapier let users submit an empty step and hit a confusing
HTTP 400 at run time. Search Memories and Get Memories already require user_id;
this makes Add Memory consistent and surfaces the requirement in the editor
before the Zap runs.
