Added a guest haptics preference and surfaced it in both the settings sheet and /settings, with safe device detection

and a reduced‑motion guard. Haptics now honor the toggle and still fall back gracefully on iOS (switch disabled when
  navigator.vibrate isn’t available).

  What changed

  - Haptics preference storage + gating: resources/js/guest/lib/haptics.ts
  - Preference hook: resources/js/guest/hooks/useHapticsPreference.ts
  - Settings UI toggle in sheet + page: resources/js/guest/components/settings-sheet.tsx, resources/js/guest/pages/
    SettingsPage.tsx
  - i18n labels: resources/js/guest/i18n/messages.ts
  - Tests: resources/js/guest/lib/__tests__/haptics.test.ts
