Valid config and update how configuration is saved

Problem/Motivation

So currently the node_types is saved like

article: article
basic: 0

So this means if a new content type is added this config is out of sync.

We should just save the checked inputs vs all so it would just be like

- article

Will need a small upgrade hook too.

Should validate the other config schema while at it.
