  RevenueChartWidget, PaymentFailureRateWidget (Payment module) dashboard
  widgets, auto-registered via each plugin's existing discoverWidgets().

- 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.
