fix: step 6 should only start infrastructure services

- Explicitly list infrastructure services in docker compose up command
- Exclude frontend, backend, and nginx from Step 6 startup
- Prevents frontend build failure when only infrastructure is needed
- Frontend/backend are started separately in Steps 11-12

Fixes: frontend service build failure in Step 6 when npm ci fails
Infrastructure services: timescaledb, redis, kafka, etcd, minio, milvus
