printedparts: kiosk tag prefix + labels use the gage lab tag

Kiosk item lookup shows a fixed "WJ" prefix addon so operators type only the
number off the label. The label page - and the detail "Part Label" button,
renamed from "Bin Label" - now barcodes and prints the gage lab tag, falling
back to the internal item code when a part has no tag assigned.
