**What**
Allow a customer to complete a requested order edit.
**Test**
- Unit tests complete flow
- Unit tests medusa react
- Integration tests of order edit completion
FIXES CORE-501
**What**
Improve transform query middleware management of the allowed fields and relations in order to improve security upon access data
FIXES CORE-651
**what**
Support confirm of an order edit:
Upon confirmation, the items of the original order are detached and the items from the order edit are attached to the order.
The order total is recomputed with the correct total which can defer from the paid_total and refundable_amount (based on the paid_total)
**Tests**
- Unit tests medusa-js and medusa-react as well as the core
- Integration test of the confirmation flow which check that the order edit is properly confirmed and can be confirmed idempotently. Also validate the totals and that the order items correspond to the order edit items. Also validate the order totals.

- When no item change already exists
