vLLM now works like the in-process engines: tag a model entry with backend:vllm and it's
served by its own path, under its own name (VllmBackend uses the requested model name as
--served-model-name, resolved from models.json). vllm.model_id/model_path are optional
(single-model convenience only); default blank -> no synthetic /v1/models entry, no alias
auto-routing, pin-only. Docs + admin card updated to reflect the model-list flow.
