feat(waf): Regel direkt aus Alert als Ausnahme hinzufügen — v1.2.78

Jede Alert-Zeile hat jetzt einen "Als Ausnahme"-Button. Klick:
1. Lädt aktuelle WAF-Config der betroffenen Domain
2. Fügt die Rule-ID zu rule_exclusions hinzu (dedupliziert)
3. Speichert via PUT /waf/configs/:domain_id → triggert HAProxy-Reload
4. Erfolgsmeldung + WAF-Config-Query invalidiert

Button disabled wenn domain_id fehlt (Domain nicht aufgelöst) oder Viewer-Rolle.
