feat(install): block port 3000 after Forgejo install, English instructions

Browse source 
- Automatically add iptables DOCKER-USER DROP rule for port 3000 so
  Forgejo is only reachable via NPM proxy, not directly from the internet
- Rewrite post-install instructions in English with all 6 NPM setup steps
  including SSL config and correct ROOT_URL / SSH Port values
