feat(gateway): expose embedding model catalog

[marius-kilocode]

Summary

Expose the Kilo-hosted embedding model catalog through the gateway so clients can fetch supported indexing models from Cloud instead of hardcoding the list.

Verification

Manual API testing was not run locally. The endpoint is static and covered by a focused route test.

Reviewer Notes

This is paired with the kilocode PR that switches indexing settings to consume /api/gateway/embedding-models with a bundled fallback.
