fix(litellm): restore DATABASE_URL env var lost when adopting the drifted live deployment

kubectl apply replaced the live pod's env list wholesale with what was
in this file (which never had DATABASE_URL, despite the
litellm-db-credentials secret already existing) — litellm's proxy
requires DB connectivity to fully start regardless of config.yaml
content, so this caused an immediate crash loop. Restored it.
