/**
 * iOS-spezifischer Recovery-Sheet wenn NEFilter-Aktivierung mit
 * NEFilterErrorDomain code 5 (Permission denied) fehlschlägt.
 *
 * iOS cached "Refuser" einmalig — der System-Dialog kommt beim normalen
 * activateUrlFilter nicht mehr. Sheet bietet zwei Recovery-Pfade:
 *  1. „Erneut versuchen" → ruft protection.resetUrlFilter() (Swift macht
 *     removeFromPreferences + frisches saveToPreferences → meist frischer Dialog)
 *  2. „Einstellungen öffnen" → Deep-Link via Linking.openURL('app-settings:')
 *     wenn auch Reset nicht hilft (z.B. Screen-Time-Restrictions)
 *
 * Plus ein 3-Step-Fallback-Hinweis für den Härtefall (App neu installieren).
