docs(proxy): add config-only docker compose setup to quickstart

[devin-ai-integration]

Summary

Addresses litellm#35084: the quickstart only offered a Compose path for the Postgres-backed stack, so anyone wanting a pure litellm_config.yaml setup was left with a bare docker run at the bottom of the page.

Adds static/docker-compose-config.yml (served at https://docs.litellm.ai/docker-compose-config.yml, mirroring the existing docker-compose.yml): a single litellm service on the non-database image, mounting ./litellm_config.yaml at /app/config.yaml and passing --config=/app/config.yaml. No Postgres, no LITELLM_SALT_KEY (nothing is stored encrypted in a DB in this mode); provider keys come from the environment, defaulted so Compose does not warn when unset:

environment:
  LITELLM_MASTER_KEY: sk-1234
  OPENAI_API_KEY: ${OPENAI_API_KEY:-}
volumes:
  - ./litellm_config.yaml:/app/config.yaml
command: ["--config=/app/config.yaml"]

The "Running without a database" section now tabs between Docker Compose and docker run. It also corrects a gap the issue implies: verified locally that with no DB the Admin UI login fails with "Authentication Error, Not connected to DB!", so the docs say so explicitly and point at GET /v1/models with the master key as the verification step instead.

Validated by running the new compose file with a litellm_config.yaml: /health/liveliness returns 200 and /v1/models lists the configured model. npm run build passes (only pre-existing warnings).
