The vehicle page search previously only filtered category names at the
currently rendered level. Add a server-side cross-tree search over what's
already drilled into the DB.
New GET /categories/search/:vehicleId?q= returns two sections:
- categories: name-matched leaves UNION the leaf categories that contain a
matching part (with hit count). "fren balatası" matches no leaf by name —
the pads are parts under leaves like "Disk freni" — so the union surfaces
the right leaves.
- parts: parts matching every token on name, or the raw query on oem_code,
with OEM + leaf + breadcrumb.
Pure DB read (no upstream drill); a treeIncomplete hint is returned when the
vehicle's tree looks barely drilled. Frontend adds a debounced search box on
the vehicle page that hides the normal browse while active.
