Remove react dependency

[fonsp]

We have almost no frontend code in this codebase, so we can probably get rid of the react dependency.

It would be great if we can also avoid webpack and its configuration. Maybe switch from electron-builder to https://www.electronforge.io/ ? They recently became the "official" electron builder, migrating from github.com/electron-userland to github.com/electron

Removing webpack could be trickier than I anticipated, since it handles all the typescript compilation and module management
