Create atomic desktop components

[mike-kiss]

Currently in the desktop app, there are a number of places where we are re-defining overrides for MUI components (try searching the code for "${classes.button}"). This is not very DRY, so let's create our own component library where these overrides can have a single home. Known MUI components we likely want to create wrappers for:

• Button
• Typography
• Icon
• IconButton
• Grid
• Link?
• Avatar
• Progressbar
• CircularProgress
• Container
• Modal
• Label
• Input
