Addresses long-term fix from insight cmpifhxfs000lvze9cy6ne0tx: users in
deep category trees had no orientation cue beyond a single back button.
- Breadcrumb derived from the cached /categories/tree/<vehicleId> response.
When the cache is warm (user came from the vehicle page), the full ancestry
renders; otherwise it falls back gracefully to "Vehicle → Current".
- Vehicle label fetched via the same query key already used by the vehicle
page, so the request is deduped.
- Back button now prefers the breadcrumb parent (resolved synchronously from
cache) over `data.parentId` (which is async). Clicking back before the
category payload loads no longer dumps the user to the vehicle root.
- H1 placeholder during load swapped from a stale "Kategori Detayı" string
to an inline pulse — prevents the title from briefly displaying wrong text
before the real name resolves. Uses a span-based pulse (Skeleton is a div
and would be invalid HTML inside an h1).
Phase 3/8 of the UX audit follow-up.
