fix: correct server port config and seed default settings

- config.ts: rename nixserverPort/nixclientPort to single port, default
  HOST to 127.0.0.1 (installer binds to loopback, Apache proxies)
- index.ts: use config.server.port
- seed.ts: fix wrong default settings (nginx->apache2, bind9->powerdns,
  postfix->exim4, vsftpd->disabled)
