Marco a6edd7ff61 fix(cart): make the "Hinzugefügt" success state subtler
Was a solid bright-green fill with white text; now the same pale
success-subtle fill + success-colored text/border AddToCartInlineButton
already uses elsewhere (RelatedProducts, shop cards) — consistent, less
loud.

// a solid success-green fill with white text — same restrained pairing
// AddToCartInlineButton already uses (border-success + bg-success-subtle),
// a solid bright-green button read as too loud here. `border` (width) is
// added here too since `base` has none by default, unlike
// AddToCartInlineButton's own base which already carries a plain border.

both possible texts in the same grid cell (both invisible ones
still contribute to sizing) reserves width for whichever is
wider, so the button's box never changes size either way. */}
