fix(parcel-sync): static connection dots, legend position, mismatch labels

- ePay + eTerra pills: removed animate-ping, now show static green dot
  when connected (no more spinning appearance)
- Legend moved to top-left, hides when FeatureInfoPanel is open
  (no more overlap)
- Boundary mismatch parcels now show cadastral numbers as labels
  (orange for foreign, purple for edge parcels)
