Fix cash payment fee: use real Payfrit platform fee, not 2.25% cash handling fee

submitCash.cfm: Calculate platform fee from subtotal * PayfritFee,
store in Orders.PlatformFee and Payments.PaymentPayfritsCut on submission.

complete.cfm: Replace bogus 2.25% cash transaction fee with the real
platform fee (customer fee + business fee = 2 × PayfritFee × subtotal).
Credit full Payfrit revenue to User 0. Record business fee in
PaymentPayfritNetworkFees.
