The homepage category carousel and installments highlights matched
slot.images[i] to categoryList[i] by array index, assuming the business's
CMS upload order lines up with this site's own category sort order. It
doesn't - live data showed a laptop photo landing on "موبایل" and "لوازم
برقی" appearing on the site despite no photo ever being uploaded for it,
purely from index luck. titleFa isn't reliable either: the same laptop image
was titled "تبلت" in the CMS, contradicting its own linkUrl.
Fix: resolve each image's category from the `category` query param on its
own linkUrl (categorySlugFromLinkUrl() in slug.ts, matched against
ApiCategory.slug via the new findNodeBySlug()). The homepage carousel is now
fully slot-driven - it iterates slot.images (in the CMS's own sortOrder) and
simply omits any category with no matching image, per explicit product
direction, rather than falling back to a placeholder. Installments keeps its
curated HIGHLIGHT_IDS list with a placeholder for uncovered categories,
since that page always shows the same fixed set, but now uses the same
identity-based lookup instead of position.
