The map iframe lived inside a collapsed (max-h-0, overflow-hidden)
accordion with loading=lazy, so it often never loaded after expanding.
Mount the iframe only when the location item is open so it loads fresh,
and raise the open clamp from max-h-screen to max-h-[800px] so the map
isn't clipped on shorter viewports.
