  purchase return: look up the open return against a document
  
  selectOpenByDocumentReference returns the return still outstanding against a
  document reference - neither refunded nor rejected - or null when none is.
  
  Backs a duplicate guard on the invoice-return submit path: the same invoice was
  being submitted twice, the closest pair eight seconds apart, and finance was
  rejecting the extras by hand. A settled return deliberately does not count, since
  rejecting a return is precisely what frees the invoice to be raised again.
  
  Repository lands first so the method exists before the caller uses it.
