feat(map): exit fullscreen on marker click, then scroll to entry

When fullscreen is active, clicking a marker now triggers fsBtn.click()
to exit cleanly (handles class, body overflow, tripMap.resize + icon),
then waits 450ms for the exit animation before scrolling to the entry
and firing the highlight. Also fixes missing icon-swap CSS for
.home-map-col.is-fullscreen (was only targeting .feed-map-wrap).
