feat(storefront): galería deslizable en las tarjetas de producto del listado

Permite ver todas las imágenes de un producto desde el catálogo y los
carruseles sin entrar a la ficha: swipe con scroll-snap nativo en
móvil, flechas al pasar el mouse en escritorio (pointer-fine) y puntos
de posición. Cada imagen sigue enlazando a la ficha; productos con una
sola imagen no muestran controles. overscroll-behavior-x: contain evita
que el swipe de imágenes mueva el carrusel de productos del inicio.

Validado antes del merge con build de producción local (datos mock) y
Playwright con eventos táctiles reales a 390/320 px y 1280 px.
