fix(apple): make the device detail screen reachable

The Settings stack has a typed path of [SettingsSection], so a
NavigationLink carrying a String could never push onto it: tapping a device
in the list did nothing. Contact detail is now a SettingsSection case, and
the path maps it to the two-level push the way the bug report screen
already does.
