More info sheet: overlay the map tap target, move the copy line below the address

The map tap target is now an OVERLAY button on top of the Map. A Map wrapped
in a Button inside a List row never received the touch, so the first attempt
left the card inert. The Map stays non-interactive and the overlay owns an
explicit rounded-rect content shape.

The copy glyph and its Copied confirmation move onto their own always-present
second line, so the confirmation can no longer reflow the address above it.
Verified: the address line's ink-pixel runs are identical with and without
the confirmation.
