Finalize "Removal of JAXB Class Not Found Fix"

- Problem: I fixed CompletableFuture.*async within the DeliveryRequest
  flow, but forgot to do the same for the DeliveryRequestStatus /
  DeliveryNotification flow.
- Solution: Ensure that all CompletableFuture.*async() invocations
  have Spring's task executor attached.
