Referral rewards: pay a hunter for bringing someone who actually hunts

PolHunter retains well and recruits badly. On 2026-09-22 it had its best day,
105 finds from 37 hunters, and had sent three people to InstantAdPay in its
whole life, all three on one member's link. Earning and sharing were separate
actions and only one of them paid.

Bringing someone is now the best-paid thing on the board, and the card sits
first in the mission list rather than on a promo page nobody opens. A flat 3
POL the first time someone they brought finds a code, then 20% on top of that
person's finds for their first 30 days, paid from the pool and never taken out
of the newcomer's drip.

Who counts as "brought by me" is the sponsor they actually joined
InstantAdPay under, handed over in the sign-in payload, so the bounty and the
commission always land on the same person. The bounty only pays for a member
who is genuinely new, once per person, and referral drips have their own daily
ceiling so a good referral day can never starve the finds.

Also: findsToday defaulted its day argument to undefined and silently returned
zero for every caller that omitted it.
