fix: show untyped CV items in both work and personal views

Items without a type field (existing data before type feature was added)
were only appearing in "personal" filtered views. Since the /cv/ page uses
work-only variants, all existing untyped data was hidden. Changed filtering
so untyped items appear in both work and personal views.

Also guard cv.skills dictsort in cv.njk against undefined.
