parseFordGroupsFromHtml leaked header/breadcrumb links into the category list as pseudo-categories that drill to nothing: Hyundai/Kia "Portal" (portal.action), logout, and Nissan "Repair & Maintenance Information" (external https://eu.nissan.biz/). Skip these in both the primary tr-row parser and the <a href> fallback. Real categories (group.action / group-detail.action / json-(main|sub)-group.action) are unaffected, and Volvo's vin-group.action?...group1=... real categories are kept.
