Technical summary

Jupyter AI startup can fail with a GlobalConfig ValidationError because embeddings_fields is required but absent in saved config.

Give embeddings_fields a default empty mapping/list or migrate missing config before Pydantic validation.

This issue is about configuration compatibility, so missing embeddings_fields should be treated as older config rather than a fatal user error.

The snippet uses native project logic; the provider schema row is narrowed to the fields Jupyter AI uses before the embeddings settings are rendered. The helper result is consumed directly by the patched code path.

After applying the patch, keep the import smoke test for the affected package:

python3 -c "import jupyter_ai; print('smoke test OK')"
