Don't require payment review by default in Phortune

Summary: We've processed some payments without anything going wrong now, and in the Phacility case we control all the payment amounts and the goods are essentially-virtual and billed-after-delivery anyway, so abuse is fairly difficult/pointless and presumably unlikely.

Test Plan: Paid an invoice and saw it go to completed immediately.
