Tester reports: nach 'Don't Allow' im System-Dialog reagiert Re-Request nicht (NEFilter), plus FamilyControls wirft NSCocoaErrorDomain:4099 (XPC-Daemon-Failure). Mehrere TestFlight-User betroffen. Swift native: - resetUrlFilter: 800ms delay nach remove + 3x retry-loop bei code 5 - activateFamilyControls: 3x retry-loop mit Backoff bei 4099 JS: - PermissionDeniedSheet generic via variant prop (nefilter|family_controls) - Blocker + Onboarding: 4099-detect → Recovery-Sheet mit 3-Step-Fallback I18n DE/EN/FR/AR: blocker.family_controls_error.* keys
