Fix the undefined model reference before merging. model_name is no longer declared but is still used by both streaming and non-streaming response paths, so the handler does not compile. Restore the model_name declaration or consistently update those references to model_id.

only still-valid issues, skip the rest with a brief reason, keep changes
minimal, and validate.

In `@src/openhuman/inference/http/server.rs` around lines 147 - 152, Restore the
model_name binding from req.model before constructing the ModelRequest, so both
streaming and non-streaming response paths can continue using it without an
undeclared-variable error. Keep the existing model_request construction and
token handling unchanged.

Apply the same fix in `@src/openhuman/inference/http/server.rs` around lines 150 -
151.
