DevRecDX? - Simplify code base. Move non-Django scripts into "scripts" folder

If something is not deployed on the server as an app, it doesn't need to be examined for security vunerabilities etc

Basically knowing this won't be run on a server is useful as it reduces the amount of code to audit

So should probably break up scripts into those that are used on server, and those that are for generating test data etc

Also move out any dependencies required by them
