fix(admin): map Winter icon-* names onto lucide for plugin navigation

Ported plugins send Winter icon-* class names on nav and settings; the SPA
never loads Font Awesome, so unknown names rendered as empty squares. Map
BM Studies, Quizzes, icon-pencil, and a closed Winter backend alias table
onto named @lucide/vue 1.17.0 exports, keep Square for unknown names, and
rebuild the embedded boardwalk dist.
