📄 Description

The proxy (catch-all), responses, and embeddings endpoints only looked up models in the OPENAI_MODELS cache, which contains real backend models but not workspace alias models. When an alias model was requested, it was not found and the request either fell back to the wrong backend (idx=0) or the upstream returned 404 for the unrecognized alias name.

Now all three endpoints check the Models DB for workspace aliases and resolve base_model_id before routing, matching the existing behavior in generate_chat_completion.

Fixes #22134
