Qualified dashboards promote the next unqualified position in their leg

Instead of only pointing at the team rotator, a qualified member's share
card now runs the moving-link wave automatically: breadth-first,
left-to-right, the first position below them with fewer than 2 directs
becomes "next in line" — their QR, page link, and join CTA all carry
that position's ID. When it qualifies, the card rotates to the next one.
Falls back to the team rotator when the whole leg is qualified.
