Move Legal pages to their own module

[lindapaiste]

Changes:

• Move files for the "legal" section to a new directory client/modules/Legal
• Change the import path in client/routes.jsx

I want to cleanup some of this code but first let's isolate it. Nothing in /IDE depends on /Legal and vice-versa, so it makes sense to keep them separate.

I have verified that this pull request:

• has no linting errors (npm run lint)
• has no test errors (npm run test)
• is from a uniquely-named feature branch and is up to date with the develop branch.
• is descriptively named and links to an issue number, i.e. Fixes #123

Thanks so much for pointing this out! Consolidating all of the "legal" related files here is a great update!
