Makes the depth-matched payment routing visible per member: walks their
subtree and shows who is ONE upgrade away from paying them (member at
depth D whose level equals D — their next upgrade routes to this
position first), the exact amounts from the contract's cost tables
(exposed via the member API), eligibility warnings (needs 2 directs /
needs level X), a ready-now total, and whether it covers their own next
upgrade. Members building toward their pay-you level are counted, with
the takeaway line "helping your leg upgrade IS your income."
