Previously, if the additional-mirror S3/Garage check couldn't find
~/docker/garage/.env on the remote box, it just warned and silently
dropped the mirror — forcing a full re-run (and re-entering every
already-answered prompt: destinations, passwords, schedule, B2,
DR-spare, etc.) once Garage was actually installed.
Wrap the S3/SFTP branch in a loop so the "Garage isn't installed yet"
case now offers a real 3-way choice:
1) install Garage in another session, then retry the same .env check
without leaving this script
2) fall back to SFTP for this one mirror, reusing the already-resolved
destination host/port/user/mirror-name with no re-prompting
3) skip just this mirror (default — safe for UNATTENDED, which
resolves to this automatically since prompt_text returns its
default without blocking)
Everything else install_backup() has already collected lives outside
this loop, so none of it is at risk regardless of which of the three
exits it via.
Verified against a standalone harness reproducing the state machine
with a mocked ssh (empty .env vs. populated .env after a simulated
install) and prompt_text, covering all three interactive choices, the
blank/Enter default, and UNATTENDED mode (confirms the blocking
"press Enter to retry" read is unreachable there since prompt_text
resolves choice 1's prompt to default "3" without waiting on stdin).
