[Barcode Scanner] Switch Camera Improvements

[toupper]

Description

Multiple clicks on the camera switch seem to queue up, and after that, it switches cameras for a while

Steps

1. Go to Orders
2. Tap on the Barcode Scanner button
3. After providing permissions to camera, tap multiple times to switch camera, see behavior above.

Expected

Do not queue events, disable the button until the camera is switched.

Maybe would be best to disable button until the switch of the deviceInput is changed?
