build(client): switch to vite + electron-forge, plus misc

- vite (including PWA setup)
- electron-forge
- switch eslint base config from erb directly to airbnb-typescript
- adjust injected constants to vite
- consistently prefix injected constants with two underscores
- adjust gql tag import
- migrate preload to TypeScript

Regression:
- with electron-forge there is no way to get auto-updates for AppImage, this will be broken for the foreseeable future
