Replace Center-in-Expanded / SliverFillRemaining empty states in the
notifications and devices lists with compact, centered inline text so
status widgets below remain visible without scrolling. Also align
notification filter chips to match the devices list spacing.

- 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

Adds a responsive Home screen combining the notification list with a
device summary panel and ARP scanner status, visible side-by-side on
wide screens and stacked on narrow ones.
Backend:
- New GET /api/devices/summary endpoint returning registered device
counts and "seen in last 24h / 7 days" breakdowns by registration
status
- Migration 07 adds indexes on (is_registered) and (last_seen,
is_registered) so summary queries use index range scans instead of
full table scans
Frontend:
- HomeScreen replaces NotificationList, embedding notifications,
device summary card, and ArpScannerCard in a LayoutBuilder-driven
two-column (≥700 px) or single-column layout
- ArpScannerCard extracted to a shared public widget reused by both
HomeScreen and StatusScreen
- Nav rail entry renamed to "Home" with home icon
