[NU-1724] Statistics fixes

[ForrestFairy]

Describe your changes

All links will include correlationId so if we need to split links, we'll know which are from the same time and should be merged and which are from new request. Introducing DesignerUptime statistic to check how long is designer active. If no scenarios are present we will still send all statistics, just with 0s. Max and min stats were the other way round - fix.
