Address post-merge UI feedback on the first-run setup screen — the first
screen any new admin sees:
- Use the bundled PicPeak logo (same asset the login page falls back to)
on the cream brand plate instead of the generic lucide Sparkles icon.
- Split the flow into two steps: step 1 takes only the one-time setup
token, with the `docker compose logs backend | grep -i "setup token"`
recovery command shown prominently (with a copy button) directly under
the field, plus a docs link for when the logs have rotated away; step 2
collects email + password. A rejected token bounces back to step 1.
en/de strings added; other locales fall back to en.
