feat: v1.3.0 — banner notifications, quick-access, swipe navigation, bug fixes

Added:
- Expired/expiring product banner alerts with use, throw, edit, dismiss actions
- Priority-sorted notifications (expired > expiring > suspicious qty > predictions)
- Touch swipe navigation for banner with dot indicators and arrow buttons
- Quick-access buttons on inventory (4 recent + 8 popular products)
- Auto-refresh banner every 5 min on dashboard
- Edit expiry dates directly from expired/expiring notifications

Fixed:
- Ignore negative BLE scale readings
- Banner re-appearing after edit (confirmation now persisted)
- False consumption predictions when inventory was manually edited
- Kiosk overlay no longer blocks web app header
