feat(catalog): implement step-by-step navigation for offers and suppliers

- Transform offers/index.vue to show products list with sparkline charts
- Create nested routes for offers: /offers → /offers/[productId] → /offers/[productId]/[hubId]
- Create nested routes for suppliers: /suppliers → /suppliers/[supplierId] → /suppliers/[supplierId]/[productId] → /suppliers/[supplierId]/[productId]/[hubId]
- Add OffersBreadcrumbs and SuppliersBreadcrumbs components for navigation
- Update HubCard to accept custom linkTo prop
- Key difference: Suppliers calculation uses FindRoutes (single source), Offers uses FindProductRoutes (all sources)
