Zareian d7d168e82f admin: cancel a pending order, refund a paid one
There was no way to take an order back: staff could only edit the
status by hand, and turning 'paid' into 'failed' left the credits,
heart days or subscription days the order had given. Two OrderAdmin
actions now do it:
- cancel a pending order (a payment that does arrive later still counts);
- refund a paid order, after a confirmation page: takes back the pack's
  unspent credits (never below zero), its heart days, or the plan's
  subscription days, and undoes the referrer's commission.
The money itself is returned in the Zarinpal / Bazaar panel; the action
says so. Status is read-only in the order form. Steps in
docs/operations.md.
