Inventory receipt dates now use actual receipt

Inventory receivedAt and the landed cost date now use a supply shipment’s actualReceivedDate, falling back to the delivered date when receipt is unknown. Previously they used the delivered date. Reports or integrations that treated warehouse delivery as inventory receipt must account for the distinction.

Advancing a shipment to In Transit, Delivered, or Received records the corresponding date. Pass statusDate when recording a historical transition so it uses the intended date.
