/my: default to pitch on link visits + big Join button above the fold

- default tab now: shared /my/<id> link -> Team Build pitch; form lookup /
  returning member on bare /my / #dash link -> dashboard (replaces the flaky
  "have you seen this ID before" heuristic that dumped returning prospects
  straight into the dashboard).
- added a big gold "Join the Team" CTA in the hero (right column), above the
  fold, so a sold visitor can join without scrolling past the video.
