Subject: [PATCH] feat(keyboard): add haptic feedback toggle in keyboard
 sub-settings #638
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add hapticFeedback case to UserInteractiveState enum
- Add 'Haptic feedback' toggle to Functionality section in
  languageSettingsData (keyboard sub-settings page, not main settings)
- Handle save/load of langCode+HapticFeedback UserDefaults key in
  InfoChildTableViewCell (switchDidChange + fetchSwitchStateForCell)
- Add hapticFeedbackIsEnabled() in KeyboardViewController reading from
  shared UserDefaults container
- Guard haptic block behind hapticFeedbackIsEnabled() — off by default
- Strings hard-coded for now pending Scribe-i18n entry
