ProductHero: match der-eine's gallery sizing, CTA label, icon color

der-eine is the reference the whole PDP block system is meant to look
like — three concrete deviations fixed:
- Gallery was full-bleed across the whole lg:col-span-7 column; der-eine
  caps it at max-w-[28rem], centered, vertically centered at lg: — same
  treatment now, same reasoning (der-eine's own Hero.tsx comment on why).
- Hero CTA was a generic "In den Warenkorb" instead of "${product.name}
  bestellen" like der-eine's/todo-cards' own buttons (the closing
  ProductPricingPanel button already said the generic label correctly —
  matches der-eine's own two-CTA pattern, hero named, pricing-panel
  generic).
- stepRow icons render brand-yellow (STEP_ICONS, shared with Pages.layout
  content pages that want that) instead of der-eine's black
  (Focus.tsx's #231f20). Recolored via a CSS descendant-selector override
  scoped to ProductBlocks.tsx's own stepRow case, not touching the shared
  icon set or PageBlocks.tsx.
