Interleave banners between carousels, real "view all" links, bigger desktop logo

- StoreSpecialCarousels now inserts one of the two banner sections
  (TwoBanners/ThreeBanners, cycling) between every pair of carousels
  instead of stacking all carousels together with the banners fixed
  elsewhere on the page — works for any number of dynamic carousels.
- SectionTitle's action button is a real link now (actionHref), not an
  inert <button>. Each carousel's "مشاهده همه" goes to
  /products?specialId={group.id}, which renders that exact
  admin-curated group in the full product grid — store-specials groups
  have no pagination, so this is genuinely the complete set, not a
  truncated preview. Also fixed BlogCarousel's dead "وبلاگ" button the
  same way, now linking to /blog.
- Reduced FeaturedCategories' vertical padding (py-10/14 -> py-4/6).
- Desktop header logo was smaller than the mobile one (36px vs 46px) —
  bumped to 40/48px so it reads properly at desktop width.
- CONTEXT.md: document the banner-interleaving and specialId patterns.
