nhcx-payment

Add NHCX payment notices to a hospital information system or a standalone claims desk. Receive the payer's PaymentNotice, match it to its claim by the claim number, record it once, and acknowledge it at once (workflow 17 on PMJAY, the notice's own id for a generic payer), held to the pinned bundle. Starts by checking whether the app already records NHCX payments or acknowledges notices, and whether it holds the filed claim a notice names, then builds, extends or reuses only what is missing. Self-contained; needs no other skill installed. Use for payment notices, settlement, UTR, payment acknowledgement, NHCX use cases B7 and D13, flow step F12.
