Remove Flask Assets

This commit’s parent introduces a Node-based way of managing front end assets.

Nothing else is needed in the app, specifically not Flask Assets. Flask itself
automatically routes requests for `domain.tld/static/*` to the files in
`app/static`.

This also removes all the Ruby stuff.
