feat(item-card): add 'market'/'catalog' mode prop with defensive price checks

Introduces optional `mode` prop ("market"/"catalog") to conditionally render components like rarity badges. Adds defensive checks for missing price data and priceHistory properties to prevent runtime errors. New icons `Badge` and `Boxes` imported from lucide-react.
