Add complete health check implementation for Docker HEALTHCHECK and Traefik health routing with: Response fields: - status: "ok" or "degraded" - uptime_s: seconds since mothership boot - version: mothership version string - nodes_online: count of connected nodes - db: "ok" or "failing" (SELECT 1 with 100ms timeout) - load_level: 0-3 from load shedding state - reason: human-readable explanation (only when degraded) HTTP status codes: - 200 for healthy (status="ok") - 503 for degraded (status="degraded") Degraded conditions: - Database unreachable - Load level 3 sustained for >60 seconds - No nodes connected after 5 minutes uptime Docker HEALTHCHECK updated to verify status="ok" response.
