📄 Description

Summary

Fix model listing for GitHub Models in OpenAI-compatible connections.

Open WebUI currently requests <base_url>/models for provider model refresh. For GitHub Models, this fails when base URL is https://models.github.ai/inference, because model catalog is exposed at:

https://models.github.ai/catalog/models

This PR adds provider-aware endpoint resolution for model listing while preserving existing behavior for other providers.

Changes

Added get_models_endpoint(url: str) helper in backend/open_webui/routers/openai.py
If URL contains models.github.ai, model list endpoint is mapped to:
- https://models.github.ai/catalog/models
Replaced hardcoded f"{url}/models" calls with get_models_endpoint(url) in:
- get_all_models_responses
- get_models
- verify_connection

Why

Without this mapping, model refresh fails with 404/content-type parsing errors against .../inference/models.

Validation

Python syntax check:
- python3 -m py_compile backend/open_webui/routers/openai.py

Closes #21257
