- we were already
- statically declaring "NSCameraUsageDescription" in the Info.plist
- this used to be enough in the past
- codesigning with an entitlements.plist that declares "com.apple.security.device.camera"
- I believe this is required for notarization to pass for an app that declares "NSCameraUsageDescription".
- previously this was enough to access the camera IIRC
- in any case, if the user goes into "System Preferences">"Security & Privacy", they can manually modify permissions there
- now with this commit, we on-demand trigger at runtime the OS permission prompt
- making it much easier for users to actually use the camera
- note: if you run via the Terminal, e.g. `$ $HOME/Desktop/Electrum.app/Contents/MacOS/run_electrum`,
then it will be the Terminal app that requires the camera permission. If you run by double-clicking Electrum.app,
then Electrum.app will be the "app" that requires the camera permission.
- `$ tccutil reset Camera` can be used to clear permissions for all apps (back to the Qt::PermissionStatus::Undetermined state)
ref https://doc.qt.io/qt-6.5/qcoreapplication.html#requestPermission-1
The user should still be able to open the Preferences dialog, despite the camera functionality being broken.

There was no ability to read qr codes contained in image files. This
could lead to confusion in some contexts, as `on_file_input()` of
ScanQRTextEdit will read the whole content of the file (instead of
looking for qr codes). The revealer plugin for example generates png
files containing qr codes and uses the `ScanQRTextEdit` to get user
input, for the user it would seem logical to click on 'Read from file'
to load the generated file, however this will result in the wrong data
being loaded. Having the option to explicitly load a QR from file makes
this clear. Also it seems useful, especially considering reading QR from
screenshots doesn't work on wayland.
