Select a screen region and decode the QR code in it to the clipboard, so
an otpauth:// setup code shown on screen no longer needs a phone.
The decoded value is only ever placed on the clipboard, and marked
sensitive so clipboard history skips it. Decoding is restricted to QR so
a stray barcode elsewhere on screen can't take the clipboard instead.
