Neue Branding-Page und Gäste-PWA reagiert nun auf Branding-Einstellungen vom event-admin. Implemented local Google Fonts pipeline and admin UI selects for branding and invites.

- Added fonts:sync-google command (uses GOOGLE_FONTS_API_KEY, generates /public/fonts/google files, manifest, CSS, cache flush) and
    exposed manifest via new GET /api/v1/tenant/fonts endpoint with fallbacks for existing local fonts.
  - Imported generated fonts CSS, added API client + font loader hook, and wired branding page font fields to searchable selects (with
    custom override) that auto-load selected fonts.
  - Invites layout editor now offers font selection per element with runtime font loading for previews/export alignment.
  - New tests cover font sync command and font manifest API.

  Tests run: php artisan test --filter=Fonts --testsuite=Feature.
  Note: repository already has other modified files (e.g., EventPublicController, SettingsStoreRequest, guest components, etc.); left
  untouched. Run php artisan fonts:sync-google after setting the API key to populate /public/fonts/google.
