Let verify tutorial demo card fill the /verify card width

On /verify the VerifyTutorial rendered without the stacked prop, so its
DemoStage stayed capped at max-w-md inside the much wider max-w-2xl
verifier panel, leaving the animated campaign card looking too small for
its parent. Pass stacked so the demo spans the full container width.
