refactor(firewall): improve port completion list

- Remove FTP (21) - not recommended for production use
- Remove all Dev-Server entries (3000, 5000) - not relevant for firewall rules
- Update descriptions for ports 80, 8000, 8080 to clarify HTTP/HTTPS usage
  Changed from 'HTTP-Alt' to 'HTTP (or HTTPS w/TLS)' for clarity
