Fix country detail panel clipped by overflow-hidden ancestors

The dropdown was rendering inside the overflow-x-auto scroll container,
which forces overflow-y to clip too, making it invisible. Lifted the
detail panel above the scroll row as a separate component, with
selected state managed by GlobeCard so only one expands at a time.
