- When order is opened, paymentStatus of POLs should transition as follows:
- if "Pending" -> "Awaiting Payment"
- If not "Pending", leave as-is.
- When order transitions to Open workflow status POLs payment status and receipt changes to "Awaiting Payment" and "Awaiting Receipt" respectively.
- Unit and API tests have been updated as needed
