Add user feedback when a scan is ignored

When scanning books into a tray:

A barcode not in voyager should be a hard stop. The system should not be able to proceed by just scanning something else (e.g. pressing enter).
Any other failure should flash a message on the screen to the user. This is not currently done for repeat barcode scans or for bad barcodes.
Any failure should play a sound to alert the user.
