Fix stale Models docs links in config panel

[siewcapital]

Summary

• update the Models section learn-more links for Chat, Autocomplete, and Edit to the current ide-extensions/.../quick-start docs routes
• update model setup links in the same section to ide-extensions/.../model-setup
• add a focused regression test to verify all six links point at the expected routes and do not contain /docs/

Why

The links in the Models panel were still pointing at older paths. This aligns the UI with the current docs structure and prevents regressions.

Closes #11126.

Validation

• npm test -- src/pages/config/sections/ModelsSection.test.tsx (from gui/) → fails in this local env due to unresolved transitive module imports from core test graph (partial-json)
• git diff --check

@siewcapital thanks for the link fixes!

Could you update the tests to use imported MODEL_DOCS_URLS or similar to prevent 2 sources of truth? Or feel free to remove the test file in this case.
