Make ship-queue ready refuse when its READY note doesn't reach origin (GST-2242) (#4254)

* Make ship-queue ready refuse when its READY note doesn't reach origin (GST-2242)

ready exited 0 and printed "notes pushed" even when the READY note never reached origin, so land refused the pin with QUEUE_NOT_READY (#4245). The notes writer now reads origin's ref back after each push, and train ready refuses with QUEUE_READY_NOTE_UNPUSHED when origin still lacks the note after three tries.
