Automatically adjust order status based on poLine's paymentStatus and receivingStatus

Overview:
PO status should automatically be updated to "Closed" (reason for closure is "Complete") when the following conditions are met:

• the order has

  workflowStatus == "Open"

• all PoLines have:

  (paymentStatus == "Not required" OR paymentStatus == "Fully paid") 
  AND 
  (receivingStatus == "Fully received" OR receivingStatus == "Receiving not required")
  

PO status should automatically be updated to "Open" when the following conditions are met:

• the order has

  workflowStatus == "Closed"

• not all PoLines have:

  (paymentStatus == "Not required" OR paymentStatus == "Fully paid") 
  AND 
  (receivingStatus == "Fully received" OR receivingStatus == "Receiving not required")
  

dennisbridges to check with the small group on whether a notification is required/desired in this case, and the preferred mechanism for such notifications (toast/email/confirmation modal/etc.) If any work is required for notifications it will be handled in a separate story.

We've discussed using the vertx event-bus to manage the state of the fields which contain summary information (See https://issues.folio.org/browse/MODORDERS-173). That approach seems like a good fit for this situation...

• When a PoLine's (paymentStatus or receivingStatus) are updated, fire an event. (PUT /orders/order-lines)
• The event will trigger a handler that will update the order's workflowStatus if needed (based on the criteria above)

Acceptance criteria:

• The business logic described above has been implemented
• Unit tests have been updated
• API tests have been updated
