Quantity is server-computed under a reserved key a request body cannot reach, and pushed through the existing amend path — so Stripe's CREATE_PRORATIONS charges days added and credits days released. Also refuses to drop a mail add-on mailboxes are still using, and stops a billing group changing add-ons it only inherits.
