Y axis width control on all x=time panels

[leeoniya]

some panels dont support y axis width control via override, which makes them impossible to align vertically with ones that do.

StatusHistory
StateTimeline
Heatmap

StatusHistory is a bit different cause it grows its visible time range to fit the edge cells, so we should add control for allowing them to be cut in half as well? not great, but maybe.

Happy to see some movement.
Meanwhile I would like to make a proposal. For multiple panels with the same Y-Axis, the information conveyed would be redundant.
How about this?
Only one Y-Axis for two different panels.

This is, how it looked before:

This is a grafana screenshot:

In Windows Paint I reduced the Y-Axis.

It is just a detail, but it makes it more easy to understand. And the is no Y-Axis redundancy.
