Referrals only pay for people who did not exist before

The new-member gate was refNewDays: 30, a rolling window, on a site whose
oldest account is 19 days old. It therefore excluded nobody. Every referral
payment made today, 8.67 POL across nine people, went to a sponsor for an
existing member hunting. Not one was an acquisition, which is the entire
purpose of the mission.

The gate is now an absolute date, refNewAfter, set to the morning the mission
went live. Anyone whose account predates that moment was already a member by
definition and can never earn their sponsor a bounty, a match or the launch
bonus, however much they hunt. The 30-day window stays as a secondary rule so a
dormant signup cannot trigger a bounty a year later.
