OpenAI Inference Proxy PUT

Proxy requests to OpenAI-compatible inference endpoints.

All inference requests must resolve to a VirtualModel. The platform’s provider reconciler auto-creates an implicit autoprovisioned VirtualModel for every served model entity (named after the entity, with default_model_entity set to the entity ref) so this is the typical case; operators can also create custom VirtualModels for routing, plugin chains, LoRA escape-hatches, etc. Requests for which no VirtualModel can be found return 404.
