fix(license): Rejection-Reason anzeigen + Placeholder NETC- korrigieren

Wenn der License-Server valid:false zurückgibt, wird payload.reason
jetzt als roter Alert angezeigt — bisher war der Grund nicht sichtbar
und der Operator sah nur "Abgelaufen" ohne Erklärung.

Formular-Placeholder NMG-XXXX → NETC-XXXX (mail-gateway copy-paste).
