Node.js 17+ changed DNS resolution to prefer IPv6 over IPv4. When running
in PM2 cluster mode, this causes "ECONNREFUSED ::1:8080" errors if the
backend only listens on IPv4 (127.0.0.1).
This fix sets dns.setDefaultResultOrder('ipv4first') at the very start
of the SSR bootstrap to ensure localhost resolves to IPv4.
