[BWA-108] Don't Show QR Code Scan Link When Camera Is Unauthorized

BWA-108

📔 Objective

This PR adds a check for camera authorization when setting the ManualEntryState.deviceSupportsCamera. Previously, this was true when the device had a camera even if the user had denied access. Now it will be false if there is no camera present or the user has denied access to the camera (either by initially saying No to the dialog asking for authorization, or if they agreed at first but have since turned it off in Settings).

The net-net of this change is that the Manual Entry View will not show the Scan QR code link suggestion at the bottom if the user has denied access to the camera. We already do a check for this when they hit the add code button, and they land silently on the manual entry view if the camera is not present or the access is not authorized. But previously we'd still show a Scan QR code link if the device had a camera (even when it was not authorized) and you could tap that link only to silently return to the Manual Entry View.

We could also take the approach of leaving the link but showing an error dialog when the link is tapped (something along those lines is mentioned in the ticket). I didn't see any designs for that, so I didn't pursue it for now. But it would be easy to pivot to that if we prefer to show a dialog.

📸 Screenshots

This screen existed previously (if your device did not have a camera). But it now will look like this if you have a camera but have denied access.
