Universal Links: gescannter Einzelstück-Link öffnet die App

Server liefert /.well-known/apple-app-site-association (nur /i/* beansprucht;
/l/* bleibt im Browser). iOS: Associated-Domains-Entitlement, Universal Link
(https://…/i/<UID>) wird abgefangen (onContinueUserActivity) und öffnet das
Einzelstück direkt.

Hinweis: Damit das Signieren durchläuft, muss die Capability "Associated
Domains" einmalig im Apple-Developer-Portal für die App-ID aktiv sein.
