Volvo's VIN catalog is a 3-level vin-group.action?group1=…[&group2=…] HTML
tree; PL24's json-vin-*-group.action JSON endpoints now 404. Add HTML
subgroup extraction (keep links one group-level deeper than the current
path) in ford-legacy fetchSubGroupsByPath, and route vin-group.action?group1=
nodes through getChildren (drill-first, fall back to parts) in
getCategoryWithParts. Recovers Volvo group1→group2 navigation. Leaf parts
handled separately.
