feat(waf): Phase 5 — WAF-UI (per-Domain Konfiguration) — v1.2.71

- pages/WAF/index.tsx: neue WAF-Seite mit Status-Strip,
  Domänen-Tabelle (Toggle/Mode/PL) + Konfigurations-Drawer pro Domain
  (enabled, mode, paranoia_level 1-4, rule_exclusions, trusted_proxies,
  custom_rules). Quick-Toggle ohne Drawer; Hinweis: erst Detection, dann Blocking.
- App.tsx: /waf Route + lazy import
- Sidebar.tsx: WAF im Security-Bereich
- i18n EN + DE
