test(website): expect 6 cloud model cards and refresh home product-cards baselines

The website e2e job has failed on every main push since #13431 and
#13445 landed:

- #13431 added the sixth AI model card (GPT Image 2) to /cloud but left
  cloud.spec.ts asserting toHaveCount(5).
- #13431 and #13445 were split from one branch and each regenerated the
  home-product-cards baselines against its own branch state (#13431
  without the button label centering, #13445 without the ProductCard
  Button CTA), so merged main matches neither.

Bump the model card count to 6 and regenerate the four
home-product-cards baselines against merged main inside the CI image
(mcr.microsoft.com/playwright:v1.58.1-noble, linux/amd64). The
regenerated PNGs are sha1-identical to the actual renders CI produced
at 747f76db7, and the full website e2e suite passes locally in that
container.
