Update the Settings app to enforce fresh settings are applied to preview vibrations triggered after the intensity is updated. Add preview haptics to main switch, only when touch feedback is enabled, and to the "apply ramping ringer" toggle for consistency with the rest of the screen, using ringtone intensity for preview.
