The leaf-path checks only matched /servicepart/vin_items literally, but
PL24's P5 modern catalog ships the same shape under /chemicals/vin_items,
/accessories/vin_items, /chemicals/mdl_items, etc. When user clicked a
"Rötuşkalemseti" (touch-up paint set) category whose linkPath was
/p5vwag/extern/chemicals/vin_items, the code drilled in, treated each
paint chemical's per-part URL (?partno=LLSMAX010) as a sub-category,
and inserted 228 ghost rows under it. Replace the literal substring
match with a regex that covers the whole /extern/{kind}/(vin|mdl)_items
pattern; apply to both the user-vehicle (categories.service) and the
catalog (catalog.service) flows.
