feat(ecommerce): breadcrumb real + conteos por filtro en el catalogo

ADR 0005 seccion 3 (patron Amazon), primer item de "Filtros facetados
en sidebar con breadcrumb de categoria":

- Breadcrumb (Inicio > raiz > hija) armado caminando parentId sobre la
  jerarquia real de categorias (misma que ya consume el mega-menu de
  navbar.tsx), no un dato nuevo -- CatalogClient ahora recibe el
  arreglo `categories: Category[]` completo ademas del
  `categoryGroups` ya existente
- Conteo por valor en cada filtro de la sidebar (Categoria/Marca/Edad),
  ej. "Marca (12)": se calcula client-side sobre los productos que ya
  pasan el resto de filtros activos, cada dimension excluyendose a si
  misma (patron faceted-count estandar). Sin Meilisearch por ahora,
  como preveia el ADR ("server-side simple por ahora")

Filtrado existente refactorizado a funciones matchesX() puras y
reutilizadas tanto por `filtered` como por los conteos, sin cambiar el
comportamiento de filtrado ya validado.
