The end-to-end probe against the live listmonk caught this: PUT
/api/subscribers/{id} with {"lists": []} returns 400 {"message":"Invalid
email."}, leaving the subscriber on the list. It needs {"email": ..., "lists":
[]}. The failed request was only a log warning, so the reconcile's main job —
taking lapsed members off the Members list — has never worked; only the DELETE
branch did anything, which is the branch this series just removed.
Now both classes unsubscribe successfully and keep their record.
