More info sheet: float the "Copied" capsule over the address row, not the map

The confirmation belongs to the address row, so hovering it over the map read as
belonging to the map. It now overlays the address row itself, horizontally centred
on the address line, as .overlay(alignment: .center) on the row with
allowsHitTesting(false) still keeping the row tappable through the capsule.

Verified: with the capsule up, the OCR box sits at y 1189-1231 inside the address
band (map bottom is 1075), the tint blob is centred at x 602.5 against a screen
centre of 603, the row's ink runs outside the capsule footprint are byte-identical
to the idle frame, and a real tap on the capsule's own footprint still copies.
