@yanrong-chen This is ready for your review. Please note that the QR got is not using dots as in the design. That would require a larger change.

@plasmacorral This PR updates QR code scanning and makes it part of a shared 'Receive' and 'Scan' flow. Could we kindly ask for your support to test this update against key import scanning, keystone use, etc.?
