feat: add lazy loading to product images across market components

- Implemented lazy loading for product images in CartItem, CartSummary, ProductCard, ProductDetailDialog, CheckoutPage, and StallView components.
- This enhancement improves performance by deferring the loading of off-screen images, resulting in faster initial page load times and a smoother user experience.

These changes optimize image handling across the market module, contributing to better resource management and user interaction.
