ref=<ctb-username> with an empty chain now falls back to the COMPANY ref

A valid CTB member whose self+upline program-73 entries are both empty was
keeping their raw CTB username as the ClickBaitPays ref (a nonexistent CBP
account would eat the signups — Marty caught it live with ?ref=r0705243024).
Now: endpoint code no_entry (or its reason string) -> ref=cryptoteambuild,
hub aligned to the member, fix-it nudge shown. Unknown values still pass
through verbatim for genuine legacy CBP usernames.
