[apache-http-mixin] scoreboard panel is wrong

[LauraTaylorUK]

The Apache scoreboard statuses panel is wrong in the way it displays connection/thread status.

The idle count should go down, as the others increase, but the graph is constant always stuck at the max.

I managed to make it appear correct when I edit the panel, under Graph styles, I set Stack series to Off.

(I am using Grafana 9.2.0)

Thank you.
