The configure step was two flat radio lists. It's now a From → Into layout —
the source profiles on one side, the target on the other, side by side when the
dialog has room and stacked when it doesn't — so the copy direction reads at a
glance.

Each source profile shows how many cookies it holds, counted with a bare
`COUNT(*)` that needs no decryption, so picking "You — 5,065 cookies" over
"test — 6 cookies" is an informed choice. The count is absent where the store
can't be read yet (Safari before Full Disk Access).
