Headless containers (databases, APIs, backends without a UI) belong in a
tab labelled 'Services', not 'Websites'. The categorisation logic already
routes UI-less packages there (built under #45); this finishes the rename
of the user-facing label across Apps, Marketplace, Discover and the mobile
nav, and makes 'services' the canonical tab state/query param. Old
?tab=websites bookmarks still resolve (back-compat acceptor kept).
