Flexible/responsive layout for dashboard

[janslow]

Hey, thanks for the work you've done on this project!

A recent change (sometime since 2025-04-20) has made the dashboard page unusable for my laptop's display (1470px wide), because only ~60% of the screen's is used for information, the rest is blank (the map and race control messages are below):

If I zoom out, the map is shown, but quickly dominates the screen relative to the timing data, especially if I want to see the race control messages:

In my opinion, the older layout (timing data on the left, circuit map top right and messages bottom right) was a much more effective use of the screen space
