refactor(#274): move app debug logging toggle into the Debug category

The App Settings pane carried a Debug card holding only the app-debug-logging
switch, while the Debug category already owned the log viewers. Moved the
switch next to the App debug log viewer it controls and dropped the now-empty
Debug card from App Settings.
