Runs any POST, PUT, PATCH or DELETE operation from list_operations as the connected trainer, exactly as the app would: edit or archive workouts, assign programs, log or edit a session, create assessments, diet plans and check-ins, send chat messages, cancel or move classes, create contracts and charges, update the public page, and more. Same permissions, plan limits and validation as the app; a 422 lists what is missing. It can notify students (push, e-mail) and some operations cannot be undone, so confirm with the person first. Withdrawals, bank details, password and account deletion stay in the app.
