Stop the invite being lost when a prospect clicks through the nav

Terry hit this: he shares /join/840, his prospect taps "Training" in the
nav, and by the time they reach /start the site has forgotten him and
offers the COMPANY rotation position — #148. His referral, handed to a
stranger, because the prospect read the training first.

The invite now outlives the page it landed on:

- Serving /join/<id> sets an rmc_ref cookie (30 days, Lax).
- /start reads it (or an explicit ?ref=) and shows the INVITER instead of
  the company rotation, routed by exactly the same rules the inviter's own
  page uses — direct placement if their position is set that way, else the
  next open spot in their leg. The two pages can no longer disagree.
- The Join button carries ?ref through to /join-now, which already knew how
  to place a ref correctly but was never being given one from here.
- /join-now also falls back to the cookie when it arrives with no ?ref.

The page now says whose team it is ("Invited by Member #840") rather than
an anonymous "current placement", and when the inviter is already
qualified it says plainly that the entry fills the next open spot in their
team.
