Track the join funnel end-to-end through the self-enroll page

- Self-enroll pageviews now tracked as the "joinnow" event (track.js loaded
  on the page; server whitelist + admin tiles/columns extended)
- A confirmed on-chain registration in the wallet-connect flow now auto-posts
  to the submit-id API, so every self-enroll join records a submission with
  source + clickid attribution and fires the purchase event and BeMob postback
  with no manual ID entry
- Optional name/handle field on the join page feeds the submission and the
  team Telegram alert
- Admin Traffic panel: Join-now views tile, Join-now -> Confirmed conversion,
  and a per-source Confirmed column for campaign-level ROI reading
