Adds optional handheld barcode scanning via the device camera (ZXing: QR, Data Matrix, Aztec).
Decoded text is matched to grid element id or label to trigger actions.

Needed for QR, Data Matrix, and Aztec decoding in the handheld reader.
Pins @zxing versions after yarn install.
ZXing ships ESM; include node_modules/@zxing in the babel rule.
Enable flag, camera device id, preview toggle, lock duration (defaults).
Uses current i18n label resolution; skips hidden elements.
Continuous decode, lock after hit, optional preview overlay, stops stream on destroy
PiP-style frame, status bar on dark strip at bottom of video for contrast.
Enable switch, camera list, preview, lock ms; saves metadata on OK.
Starts/stops reader with grid; adds cog menu entry and modal.
UI labels and error messages for settings and runtime status.
German translations matching the new English keys.
