Shopfloor single product transfer mobile

This module provides the mobile (barcode scanner) frontend for the single product transfer scenario in Shopfloor. It does not add new database models or menus; instead it plugs a new scenario screen into the existing Shopfloor mobile app.

On the device, the worker follows a guided flow: - Scan a source location or package. - Scan or select the product (and lot, if tracked), with a progress bar showing ongoing versus available quantities. - Set the quantity using a packaging/quantity picker, or scan product, packaging, lot, location or package barcodes. - Scan the destination location or package. - Confirm the completion screen, which returns to the start.

Each screen shows cards for the source location, product, destination location and package, with colour-coded steps (done vs. to do). A cancel button is available on the product selection and quantity screens, and a back button on the destination screen. The screen title follows the current product or the menu name.

The module also ships a demo dataset so the scenario can be tried in the Shopfloor demo app, including a sample menu entry, picking and locations. It depends on shopfloor_mobile_base and shopfloor_single_product_transfer, and only loads JavaScript assets and templates.
