webuiGenerateStorageCandidates now runs as part of webuiSystemUpdate, so
frontend/data/storage.json exists without anyone remembering to generate
it — the wizard reads it to decide whether its Storage step appears, and
the Disks view reads the same file, so the two can never disagree.
Warnings arrive from the shell joined with "; ". Rendering that verbatim
produced one run-on paragraph that buried the fstab line the user is
supposed to copy, so the card splits them back onto separate lines.
Verified on the live install with lp-shot: with one filesystem the wizard
shows "Step 1 of 4" and the Storage step is correctly absent; with a
second filesystem attached it becomes "Step 4 of 5" with the drive
carrying a "needs care" badge and both warnings legible. That also
exercises the visible-step mapping in both directions.
