Remove from the user's equipment

What your assistant is told

Remove one piece of equipment from the user's list, by the item id from get_my_equipment (the item's own id, not an equipment slug). Confirm with the user first, and read get_my_equipment in the same turn so you remove the row they meant — two places can each hold the same machine, and each is its own row. This only forgets that they have it; it touches no workout, template or logged set. Removing something already gone succeeds quietly, so a retry is safe. To move a machine between places, remove it and add it again at the other one.
