Phase 7 dashboard widgets, Gitea CI, and branded landing page (T7.1)

- BookingsTodayWidget, RecentBookingsTableWidget (Booking module) and
  RevenueChartWidget, PaymentFailureRateWidget (Payment module) dashboard
  widgets, auto-registered via each plugin's existing discoverWidgets().
- .gitea/workflows/tests.yml: Postgres-backed Pest run on push/PR.
- Landing page (resources/views/welcome.blade.php) now shows the Famous
  Linnyone4 EV logo with a single admin login link, and the Filament admin
  panel uses the same logo as its brand logo.
