feat: CrowdSec journald-Acquisition + Alarm-Quittieren/Löschen — v1.3.5

- fix(crowdsec/packaging): postinst setzt die HAProxy-Acquisition deterministisch
  auf die journald-Unit (haproxy.service) statt der cscli-setup-Datei-Default
  (/var/log/haproxy.log existiert nicht → CrowdSec las nichts → HTTP/CVE-Szenarien
  liefen leer). Self-healing auf jedem configure; admin-Custom bleibt unangetastet.
- feat(alerts): Alarme (alert_events) bulk quittieren + löschen. Migration 0045
  (acknowledged_at + Teil-Index). Dashboard-Karte zählt nur noch OFFENE (open=true)
  → Quittieren lässt die "Aktuelle Alerts"-Meldung verschwinden, History bleibt.
  Events-Tab: Row-Selection, Quittieren/Löschen (Auswahl) + "Alle quittieren",
  Status-Spalte (offen/quittiert). Audit-geloggt.
