It's this time of year again (refactoring heads up)

Some rather large changes are going to land in master soon, now is your chance to preview them and report possible issues.

See changesets here: https://git.tt-rss.org/fox/tt-rss/src/single-app-object

I wanted to remove preferences/main separate App globals and simplify things in general. Also, now there’s one less file to load on startup.

e: I also wanted to simplify things enough so that vscode code analyzer can deal with it (dojo modules is too much for it) because it works so much better for my dev setup (wsl2 and/or ssh) than phpstorm with its prehistoric deployment setup.
