fix(waf): HAProxy-Reload nach WAF-Config + cfg-file → config — v1.2.72

- handlers/waf.go: Reloader-Func; nach Upsert wird HAProxy async
  neu gerendert (SPOE-Filter erscheint/verschwindet je nach enabled-Stand)
- main.go: haproxyReloader an NewWafHandler übergeben
- haproxy.cfg.tpl: cfg-file → config (HAProxy 3.0 kennt cfg-file nicht)
