Switch camera button during device onboarding via mobile doesn't work

[KrishnaIyer]

Summary

Switch camera button during device onboarding via mobile doesn't work.
Ref: #6500

Steps to Reproduce

See https://github.com/TheThingsIndustries/lorawan-stack-support/issues/991#issuecomment-1710017134.
I have also tested this with an iPhone 12 Pro with Safari and Firefox.

Current Result

The switch camera button doesn't do anything visible on clicks.

Expected Result

The button should cycle through the cameras.
Since this is used by users to onboard devices, we need the users to be able to use the rear camera of their mobile phones.
The good thing is that I have consistently seen that it always shows the primary (rear) camera.
If we can somehow guarantee that this works, we don't even need to cycle I think.
