fix(work-order-dashboard): guard getFirstMediaUrl call on Vehicle

Vehicle model doesn't use Spatie MediaLibrary — the direct call broke
the dashboard for any WO whose vehicle has no MediaLibrary integration.
Guard with method_exists and remove the diagnostic logging + URL echo
now that the routing issue is resolved.
