- Convert ArpScannerCard to a self-managing StatefulWidget (owns its own 5s refresh + 1s tick timers), removing the duplicated state management that existed in both HomeScreen and StatusScreen
- Extract NotificationCard to home/notification_card.dart
- Extract DeviceSummaryCard (with its 1-min refresh timer) to widgets/device_summary_card.dart
- HomeScreen drops from 515 to 253 lines; StatusScreen from 82 to 19 lines
