Open the cask/keg barcode scanner when racking/packaging using the mobile app in the web view ("Breww tab")

The “scanned containers” input in the web-based racking/packaging process is intended for use with USB/Bluetooth barcode scanners, but this is visible in the “Breww tab” in the Breww mobile app. Although the mobile app’s barcode scanner can be used in other parts of the app, including the “Package” tab, it cannot be used in the web view for racking. This can be confusing, so we should allow this to be used here too.

This suggestion is based upon this question: Keg Scanner not popping up from the app window

Great news - this is now available :tada:
