Read the plan service's today from the scheduler's clock

The plan service read "today" from time.Now, so the plan-draft schedule
tests could not pin the plan_ready title on the fake clock. NewService now
takes a clock; the server passes the scheduler's Now. The plan-draft tests
read the started scheduler's fake clock and assert each plan_ready row's
title and channel alongside the existing key assertions.
