Navigation now feels more “app‑like” with

stateful tabs and reliable back behavior, and a full onboarding flow is wired in with conditional package selection
  (skips when an active package exists).

  What changed

  - Added per‑tab history + back navigation fallback to make tab switching/Back feel native (resources/js/admin/mobile/
    lib/tabHistory.ts, resources/js/admin/mobile/hooks/useBackNavigation.ts, resources/js/admin/mobile/hooks/
    useMobileNav.ts, resources/js/admin/mobile/components/MobileShell.tsx + updates across mobile pages).
  - Implemented onboarding flow pages + shared shell, and wired new routes/prefetch (resources/js/admin/mobile/welcome/
    WelcomeLandingPage.tsx, resources/js/admin/mobile/welcome/WelcomePackagesPage.tsx, resources/js/admin/mobile/
    welcome/WelcomeSummaryPage.tsx, resources/js/admin/mobile/welcome/WelcomeEventPage.tsx, resources/js/admin/mobile/
    components/OnboardingShell.tsx, resources/js/admin/router.tsx, resources/js/admin/mobile/prefetch.ts).
  - Conditional package step: packages page redirects to event setup if activePackage exists; selection stored locally
    for summary (resources/js/admin/mobile/lib/onboardingSelection.ts, resources/js/admin/mobile/welcome/
    WelcomePackagesPage.tsx).
  - Added a “Start welcome journey” CTA in the empty dashboard state (resources/js/admin/mobile/DashboardPage.tsx).
  - Added translations for onboarding shell + selected package + dashboard CTA (resources/js/admin/i18n/locales/en/
    onboarding.json, resources/js/admin/i18n/locales/de/onboarding.json, resources/js/admin/i18n/locales/en/
    management.json, resources/js/admin/i18n/locales/de/management.json).
  - Tests for new helpers/hooks (resources/js/admin/mobile/lib/tabHistory.test.ts, resources/js/admin/mobile/lib/
    onboardingSelection.test.ts, resources/js/admin/mobile/hooks/useBackNavigation.test.tsx).
