Checks run on a fixed schedule

Every check now has a fixed due time, so monitors run at the interval you set instead of drifting.

Checks are spread evenly across the interval and never run twice for the same slot.
Changing an interval takes effect right away.
A check that runs into its timeout always ends before the next one is due.
The monitor page refreshes on its own and shows the first results right after you create a monitor.
