FOUR-29322 Artisan commands fail with SQLite "unable to open database file" when queue batching is not configured

Description:
Add queue.batching config so job batching uses app DB connection

Without this, Laravel falls back to env('DB_CONNECTION','sqlite'). When
DB_CONNECTION is unset, BusServiceProvider requests the 'sqlite' connection
and php artisan route:list fails with "unable to open database file".
