Returns the current status of an order across its lifecycle. The same endpoint is used for every order event; the returned model is distinguished by the event_key and order_type fields:

• event_key = allocation, order_type = outbound → allocation started (status = locked)
• event_key = shipping, order_type = outbound → ITS/PTS transfer completed (status = completed)
• event_key = receiving, order_type = inbound → goods receipt completed (status = received)

By calling this endpoint with the order number you can see which stage the order is at and its latest status.
