Server-Config UI (aktiv/passiv) und Port-Forwarding Tipps in README

- FTP-Tab: Server Configuration mit Active/Passive Radio-Buttons
- Passive Mode: Port-Range konfigurierbar (Default 30000-31000)
- Apply-Button startet Pure-FTPd automatisch neu
- Helper-Script: serverconfig show/active/passive Kommandos
- sudoers: systemctl restart, tee und rm für Pure-FTPd Config
- README: Port-Forwarding Anleitung für Windows (netsh) und Linux (socat/iptables)
