grant_lottery_tickets_to_user incorrectly deposited the full ticket
value into manager account, not just the net value.
Additionally, royalty rate has been set to zero because Chapose won
the first lottery and grifting 8% that could instead go into the
prize pool seems unwarranted given that.
It was observed in prod that the lottery prize as tracked by the DB
had diverged from the amount held in the Lottershe manager account.
This appears to be the result of grant_lottery_tickets_to_user
adding the # of _tickets_ rather than the value of those tickets to
the manager.
