Responsive log boxes and more improvements on the Dashboard

We have added two changes to the dashboard. The most visible change is increasing the number of possible log boxes shown per row. The view has always been responsive, but with a maximum of 4 boxes per row. On higher resolutions, we now show up to 8 boxes per row. You can change Zoom settings in Windows or in the browser if you want to increase/decrease the number of boxes shown on a big screen.

To make the scale clearer, we now show the max log message counter on log boxes when in kiosk/full-screen mode. When running in normal mode, you can still hover each log box to show the counter.
