Implemented a shared mobile shell and navigation aligned to the new architecture, plus refactored the dashboard and

tab flows.

  - Added a dynamic MobileShell with sticky header (notification bell with badge, quick QR when an event is
    active, event switcher for multi-event users) and stabilized bottom tabs (home, tasks, uploads, profile)
    driven by useMobileNav (resources/js/admin/mobile/components/MobileShell.tsx, components/BottomNav.tsx, hooks/
    useMobileNav.ts).
  - Centralized event handling now supports 0/1/many-event states without auto-selecting in multi-tenant mode and
    exposes helper flags/activeSlug for consumers (resources/js/admin/context/EventContext.tsx).
  - Rebuilt the mobile dashboard into explicit states: onboarding/no-event, single-event focus, and multi-event picker
    with featured/secondary actions, KPI strip, and alerts (resources/js/admin/mobile/DashboardPage.tsx).
  - Introduced tab entry points that respect event context and prompt selection when needed (resources/js/admin/
    mobile/TasksTabPage.tsx, UploadsTabPage.tsx). Refreshed tasks/uploads detail screens to use the new shell and sync
    event selection (resources/js/admin/mobile/EventTasksPage.tsx, EventPhotosPage.tsx).
  - Updated mobile routes and existing screens to the new tab keys and header/footer behavior (resources/js/admin/
    router.tsx, mobile/* pages, i18n nav/header strings).
