ui: improve support for display scaling

[alee]

Environment: Chrome Version 118.0.5993.70 (Official Build) (64-bit)
OS: Ubuntu 22.04 LTS
resolution: 2256x1504 (3:2)
scale: 200%

I think it might be the scale that's messing things up...

edit yep, dropping scale to 1.75x or smaller fixes things

SO post for detecting and responding to scaling factors: https://stackoverflow.com/questions/46791052/detect-scale-settings-dpi-with-javascript-or-css

game UI:

shrinking down to 80% gets everything lined up properly

I can try to get a fix for this sooner rather than later today

No worries, I thought we could send this to the REUs to pickup, we should focus on the tournament setup.

It might be good to have a faq or troubleshooting page for people struggling with the interface though..

Both good ideas, we can bring it up later today
