Allow Payments/Refunds for the same amount on the same day

Currently the system is set to Block duplicate ACH payments to guard against parents getting double charged if A:) the payment was taken by autopay but did not post to the ledger or B:) To stop a parent from pushing a second payment in the case where they see an error message in the app but the payment still went through.

This is causing 2 issues. One is when siblings are being charged the same amount on the same day. It is blocking the second siblings payment from going through.

The other case is if a customer is trying to refund multiple payments for the same amount. EX if they are giving back 4 weeks of tuition that was collected in 4 $100 payments. The system blocks them from refunding $100 more then once in the same day.
