Implemented guest-only PWA using vite-plugin-pwa (the actual published package; @vite-pwa/plugin isn’t on npm) with

injectManifest, a new typed SW source, runtime caching, and a non‑blocking update toast with an action button. The
  guest shell now links a dedicated manifest and theme color, and background upload sync is managed in a single
  PwaManager component.

  Key changes (where/why)

  - vite.config.ts: added VitePWA injectManifest config, guest manifest, and output to /public so the SW can control /
    scope.
  - resources/js/guest/guest-sw.ts: new Workbox SW (precache + runtime caching for guest navigation, GET /api/v1/*,
    images, fonts) and preserves push/sync/notification logic.
  - resources/js/guest/components/PwaManager.tsx: registers SW, shows update/offline toasts, and processes the upload
    queue on sync/online.
  - resources/js/guest/components/ToastHost.tsx: action-capable toasts so update prompts can include a CTA.
  - resources/js/guest/i18n/messages.ts: added common.updateAvailable, common.updateAction, common.offlineReady.
  - resources/views/guest.blade.php: manifest + theme color + apple touch icon.
  - .gitignore: ignore generated public/guest-sw.js and public/guest.webmanifest; public/guest-sw.js removed since it’s
    now build output.
