Complete checkout POST

Call after the buyer approved in PayPal. Sayso re-checks stock and price, authorizes the payment, takes the stock and submits the capture to the shop's Guard. Big orders may wait for the owner: then `payment_status` is `AUTHORIZED_PENDING_MERCHANT_REVIEW` and the buyer is charged only if the owner agrees. Calling it again for a completed cart returns the same result; it never charges twice.
