website: drop SotaCredits import to unblock prod build

The SotaCredits.astro component was kept out of git as part of the
deferred packs UI (option B: backend lives, frontend hidden), but a
stray import + render in Base.astro made it into the previous commit
and broke the Cloudflare build. Removing the dangling reference here
restores the intended state — backend credits endpoints and i18n keys
stay; the packs section is not rendered.
