Add on-chain payment proof: live payout feed, ID verification, admin lineage tools

New chain.js reads the RM Circle contract (0x33Bd…2DAF, Polygon) via free
public RPCs — no API keys. Daily snapshot rebuilds complete payout history
from getIncomeHistory (log providers prune old history), and a 60s
eth_getLogs tail catches new payouts with tx hashes, upgrade context, and
passed-over upline IDs.

- Bridge page: "Live payment proof" feed + timed toast pop-ups for payouts
  seen in the last 15 min, every row linking to Polygonscan.
- /start: same toasts; ID submissions are now verified against the contract
  (result shown to the member, in Telegram notify, and in admin).
- Admin: on-chain member lookup (lineage to root, directs, matrix children,
  full income history) and a collapsible full matrix tree view.
