test(ui): regenerate setup-wizard visual baselines for the slow-wizard fix (#292)

The #291 wizard fix changed the step-2 error layout (+40px) but never
got a baseline pass - the visual suite only runs at the release gate,
which is exactly how the v2.11.0 release run went red (2 failed
snapshots, both `setup-wizard/step2-error`). Regenerated via `just
visual-update` on current main; all 102 visual tests pass locally in the
same Docker harness. Baseline-only change; after merge the v2.11.0 tag
will be re-cut so the release pipeline can pass.

README checked, no changes needed (test-only).
