fix(backends): Adress-Validierung für Backend-Server + Quick-Backend (v1.1.140)

Pattern-Validator lehnt offensichtlich ungültige Adressen (Sonderzeichen,
Leerzeichen) schon im Frontend ab, bevor sie HAProxy-Config-Generierung
zerstören können. Gilt für Backend-Server-Modal und Domain-Quick-Backend.
