KPI Labels don't scale

As a user
I want the labels to adjust scale automatically (from months, to days, to hours)
So that the application is valuable and accurate for high performing and developing teams alike

The issue names no files, tests, or entry points. Start by locating where KPI labels are rendered and how the current time scale is selected; define the month-to-day-to-hour transitions and verify the labels across each range. Done means labels automatically use an appropriate scale for both high-performing and developing teams.
