Fixes Weird Circle-Fill Exceeding Bounds on Tram Console (#72809)

## About The Pull Request

Hey there, do you spot the issue here?

I'm not sure when this cropped up, but it appears to have been recently
since it really irritated me when I first saw it. After a bit of toying
around with the UI, I dropped both the height/width variables of the
"fill" into the circle (the icon itself has thick enough boundaries to
where it doesn't seem weird), as well as excising the `mt` variable, as
any value I threw into it would always have some weirdness. Please do
tell me if I shouldn't have axed it, but I don't really see any ill
effect (and quite the opposite actually).
## Why It's Good For The Game

It's not as frustrating to look at anymore! Hopefully this isn't some
sort of weird localized issue, but I much prefer these results.
