fix(parcel-sync): auto-scan no-geometry + redesign UI card

- Auto-scan triggers when UAT selected + connected (no manual click needed)
- Three states: scanning spinner, found N parcels (amber alert card), all OK (green check)
- Checkbox more prominent: only shown when no-geom parcels exist
- Re-scan button available, scan result cached per siruta
- AlertTriangle icon for visual warning
