feat(map): grid QSO dialog Match button prefills the match page

- Grid-QSO dialog gains a Match action (radio-tower icon + label) in its
  header; tapping it navigates to the match page pre-filled with the tapped
  grid as the opposite station and a 24h time range, auto-starts the query,
  and scrolls the page straight to the time-range card.
- Every grid is now tappable (previously only worked grids opened the
  dialog); unworked grids show an empty QSO list instead of a hint.
