budget: price the enforced budget by the 06:00 gaming day's leisure switch

earned_time 0.16.0 made resolve(leisure=False) force pre-leisure pricing,
so the enforced call passing False would have stayed 5 h/8 h after
go-live. It now passes leisure_active(gaming day) explicitly (its own
redirectable LEISURE_FROM_PATH): the go-live gaming day is 7 h/10 h, and
00:00-05:59 on the go-live date stays pre-leisure, matching billing. The
shadow resolve keeps leisure=True.
