Dashboards discrete grid - consistent layout

[kpthatsme]

Is your feature request related to a problem?

Right now you never know what a dashboard is going to look like when you share it with a teammate, as the ordering depends on the browser size.

Describe the solution you'd like

• Dashboard items should render in generally the same order, no matter the screen width. There should be reasonable breakpoints for charts.

Describe alternatives you've considered

Additional context

I think it's an acceptable trade-off to reduce some of the flexibility we have in the free form resizing if it means more consistent sharing of info.

Thank you for your feature request – we love each and every one!

100%! Originally reported on #2762 from an internal discussion and customer feedback. We should have a strict grid that handles different screen sizes properly (e.g. allowing stacked columns). Particularly, we need to disable being able to drop dashboards anywhere.
