Support the Warehouse Receipt round-trip workflow between NIDs through Magaya Network, including the shipment return leg

When a Warehouse Receipt is sent from an origin location to another Magaya Network location (NID) that updates it and returns it as part of a shipment, the returning Warehouse Receipt should automatically update the original one at origin — reflecting the latest volume, weight, and item values — without any manual inbox retrieval.

Today the updated Warehouse Receipt is not added or updated at origin automatically; it must be pulled manually from the Magaya Network inbox, where it currently fails to save.

This idea asks that the round-trip synchronization complete automatically.
