feat(commands): supplier:check-webhook-secret deploy validator (Plan 2.6 #i)

Закрывает CV.11 audit WARN #4 (placeholder secret '__SET_ON_DEPLOY__' = silent
404 на production через verifySecret в SupplierWebhookController).

Console command для deploy-script: SELECT system_settings.supplier_webhook_secret
→ exit 1 если placeholder OR len < 32 OR row отсутствует. Иначе exit 0.

Использование: deploy-script вызывает `php artisan supplier:check-webhook-secret`
перед запуском приложения; non-zero exit прерывает deploy fail-fast.

TDD: 4 теста (placeholder rejected / short rejected / missing rejected / valid accepted).
phpstan-baseline +1 entry: Pest TestCall::artisan() PhpDoc-quirk (как
ResetDeliveredTodayCommandTest).
