Fix font loading

Summary

SUMMARY: Bugfixes "Fix font loading"

Purpose of change

Fixes #37916

Describe the solution

See commit messages.

Testing

Change in-game language to one using non-Latin alphabet (i.e. Russian, Chinese, Korean or Japanese) and see that font glyphs are displayed.

Additional context

1. We can restore Terminus Bold font after changing its internal identifier (or make font style selection configurable)

2. While working on this PR I've found out that some glyphs (like the ones with with cedilla) are not displayed properly when current Terminus font is used. I will fix it in a different PR.

Unifont:

There's a fonts.json in config, why didn't you use that? Also, I tried deleting the font and changing the json but I've still got terminus bold...

I dunno why people hate on the unifont, I happen to think it looks great. But I like single pixel width sans serif in general. Fancier fonts feel invasive for me, like I'm being told to interpret things in a certain way. In my current game I arrived at a post office I'd already cleared just before dawn and was imagining the sunrise and the cool spring air, how calm that moment would be. Then I met a wandering zombie security guard and casually speared him through a broken window. It felt relaxed, but this terminus bold would have stood in the way of that moment.

I've self-merged it as it was kinda serious issue without progress for almost a week.
