Fix: footer_ok + Monit Nginx-Check bereinigt

- footer_ok: HTTPS/self-signed Zeile entfernt (nginx hat anfangs kein HTTPS mehr)
- Mail-TLS Cert Label ergänzt damit klar ist wofür das Zertifikat ist
- Monit: Port-443-Check für nginx entfernt (kein HTTPS initial → Monit würde nginx in Loop neustarten)
