Show pump operation time in graph summary

[MyForest]

Shows operation proportion below heading "Pumps":

I did this outside the chart because I wanted the chart legend to stay focused on showing the value from the the chart line.

mmspheatpump.php is missing a <script> tag to load active-percent.js, around line 36. App doesn't load.

Thanks for spotting that @MrTimbones

That is the peril of my local version being too divergent. I'm hoping to try and get into line over the Winter.

It's fixed now.

I was about to wrap the call in a try...catch but it's a bit exciting because it's in the Promise list.

ofc I could wrap each Promise in the list as a call to the underlying function but that would defeat the simplicity of the Promise list.

I could move from all but ofc I want really want the drawChart call to work even if I'm not so bothered about the others.

It feels like I should stop doing the non-chart work in charts.js but then I'd need some other way to synchronize the change in timeInterval with invocations of the other things which would then look more exciting as you were trying to debug them. I'd end up re-inventing Eclipse!

Hmm.
