performance: Caching, deferred Tracking & externe Timeouts (H7, M12, M13)

- Navigations-Chrome (CategoryNavigation), Suche- und Newsroom-Seitendaten 300s gecacht; gemeinsamer WebPageCache-Helper (eine TTL/Key-Konvention). - Cache-Poisoning über ?page= geschlossen (Key an Paginator ausgerichtet, kein withQueryString im Cache); Newsrooms cachet nur den ungefilterten Fall und die ersten Seiten (kein unbegrenzter Key-Raum). - Detailseiten schreiben Hits/View-Events deferred nach der Response (M12); OpenAI-/Markt-/USt-ID-Aufrufe mit Connect-Timeouts und begrenzten Retries; Admin-Memo-Caches konsistent invalidiert.
