* [feature]: Support using system fonts
Uses the **experimental** queryLocalFonts API, when prompted, to get the fonts and do CSS.
Resolves#270 and #288 (by proxy)
Caveats/notes:
- This is experimental, and is only supported by Chrome/Chromium/Edgeium (see https://caniuse.com/?search=querylocalfonts)
- As far as I can tell, the only way to dynamically change the font (shown in https://wicg.github.io/local-font-access/#example-style-with-local-fonts) was by DOM manipulation; css variables did not seem to work
- This shows **all** fonts, including their variants (bold/italic/etc); given that the style names could be localized, not sure of a way to parse this (on my system, for instance, I had 859 different combinations)
- I made fonts a separate top-level setting because it was easier to manipulate without causing as many rerenders; feel free to put that back
* add permission chec
* add electron magic to support custom font
