Collapse scanner-card and pagination duplication into shared widgets

Extract ScannerStatusCard<T> and PaginationBar so the ARP/mDNS cards and the two paginated lists share one implementation each. Also fold the four UISnackbars methods over a severity enum and fix Notification.toJson serializing a method tear-off instead of the enum name. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
