Show tooltip on group instead of single graph bar (#10546)

The tooltip should show you the ratio of the group and the numbers for
both archived and created.

The tooltip's position is averaged between all the bars in the group.

<img width="335" height="262" alt="image"
src="https://github.com/user-attachments/assets/d62a4bdc-ba07-4eea-8cbf-6e42793804b2"
/>


This still throws the same errors as before. Not sure exactly what's
going on with the custom tooltip, but I'll investigate it in a
follow-up.

Closes 1-4017.
