Show which generation caught each pass-up + finish domain go-forward

Feature (Marty): live payment proof + notifications now show the
generation for upgrade pass-ups (matrix hop distance payer→recipient),
removing the "why did they get it" question. chain.genBetween() adds a
`gen` field to payout events + /api/public/payouts; rendered as a gold
"Gen N" badge in the feed, "Gen N pass-up" in toasts, and "Gen N …" in
Telegram team alerts.

Domain: rmcircle.team is now live (added to Coolify alongside
rmcircle.saasy.top, SSL issued, both serve, no redirect). Switched the
auto-tweet CTA to https://rmcircle.team.
