Returns the count and detail of failed payments that still carry a Bill.com bill id — orphaned, potentially-payable bills left behind when a payment failed after its bill was created but the automatic void could not complete (MED-1237 AC2). Read-only; used to surface the volume of orphans before running the reconciliation cleanup.

Only surfaces orphans created after the MED-1237 fix shipped. Orphans from prior occurrences have no persisted bill id and require a one-time Bill.com-side scan.
