Switch journal Docker health check from `node -e "fetch(...)"` to `curl -sf`, matching the planner. The Node.js process spawn was heavy and prone to timeout under memory pressure, causing false health check failures and 502s. Upgrade Promtail from static file scraping to Docker service discovery so logs get `service` and `container` labels. Parse Pino JSON logs to extract the `level` label, enabling Loki queries filtered by log level. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
