Subject: [PATCH] iOS: do not flicker Cancel into Authorize later while loading

The bottom slot of Authorize at Bank renders a tappable "Cancel" for the
dummy placeholder transaction, which becomes "Authorize later" (or "Done")
roughly 95 ms later in the same place and at the same size.

Both branches already ran dismissTop, so the two buttons never differed in
what they did -- only in what they said.  Hide the placeholder so the slot
keeps its height without offering a target before the transaction is known.
