server: Fix DirectDownload certificate check initial delay (#7494)

This PR adjusts the DirectDownload certificate check initial delay. Since the time unit is in hours, I think it was a mistake to schedule the initial check to be in 60 hours after management servers start - the intention was likely 60 seconds. We had turned this feature on to run hourly, not realizing we would have to wait 2.5 days to see it first run!
