Align settings page with add app page styling

- SettingsToggleRow contentPadding: 16 -> 20 (matches add app tileMode)
- SettingsTile: borderRadius -> RoundedSuperellipseBorder shape (matches add app)
- SettingsToggleRow: RoundedRectangleBorder -> RoundedSuperellipseBorder
- Add app _FormSwitchRow: add haptic feedback via selectionClick()
  (respects tactileFeedbackEnabled pref, matches settings page)
