Payment invoice selection / allocation

fix a subtle bug with simultaneous adding txns and payments across multiple terminals. A terminal processing a payment would see a simultaneously added txn in select invoice to pay screen and let the operator select it but at time of saving the txn this newly added txn would be ignored for purposes of allocation of payment. This is potentially problematic for dealers who rely on payment allocation to reconcile especially large and complex AR clients where repair to reconcile is made in-situ during reconciliation effort. This version includes a bunch of changes and guards to protect against this .  One key change is a guard to double check on construction of the txn to save to database that allocations created match exactly what the user selected and to fail the txn and reload any cached changes from database to retry : picking up any simultaneous work done on other terminals.

Other Tweaks and fixes
