[model-gateway] return 503 when all workers are circuit-broken#15611
Conversation
When all workers for a model are circuit-broken, return SERVICE_UNAVAILABLE (503) instead of model_not_found (404). This provides clearer semantics: 404 means the model doesn't exist, while 503 means the model exists but is temporarily unavailable.
