fix(NearbyScreen): TIME filter stale sort + right-align distance/age column

- TIME mode: call refresh() every 3 s so newly-heard contacts bubble up
  to the correct position; previously the list froze at the order captured
  when the filter was selected.
- All filters: right-align the distance/age value within the right column
  (width - textWidth - 2 px) instead of pinning it to a fixed left edge,
  so short strings like "5s" or "3m" sit flush with the longer ones.
