Keep offering the deferred install after backing out (#107)

* Keep offering the deferred install after backing out

The keyboard screen only advertised Ctrl+C on its first showing. Backing out
of the user step — Esc from the account form, or "No, change it" on the review
table — returned to the same screen with the hint gone and Ctrl+C back to
aborting the install, so an operator who started a direct install could no
longer switch to preparing the machine for another owner.

Offer it on every visit instead. Nothing has touched the disk at that point in
either path, and the confirmation screen still catches a stray Ctrl+C. The user
step now returns as soon as the keyboard screen arms deferral, and the main
flow re-checks the flag before choosing a branch, so a late deferral clears the
half-entered credentials and goes straight to disk selection.
