📄 Description

In multi-worker setups (multiple uvicorn workers or Kubernetes replicas), each worker maintains its own in-memory copy of CONFIG_DATA loaded at startup. When any worker saves a config change, PersistentConfig.save() writes the entire CONFIG_DATA blob to the database -- silently overwriting changes made by other workers (e.g. OpenAI connection model IDs).

This adds a get_config() call at the top of save() to re-read the latest state from the database before merging in the new value, ensuring cross-worker changes are preserved.

Fixes #22322
