Calendar view: remove hardcoded data range

[bbovenzi]

Description

In #54252 we added a calendar view. But the range of colors to count was hardcoded. Instead we should dynamically scale the color range to match the min/max counts of the data displayed on the page.

No API changes needed. The UI just need to determine a min/max of the current data the UI already has.
