Preferences connect services

[dr-bizz]

This PR is part of the Preferences Plus notifications pages. I will not go through those files, since they will have their own PR in the coming week.

Separated a lot of accordion Components into the shared folders.
Made a settings wrapper, and side menu. Also made other pages use the new shared side menu, so we don't have duplicated code.

I only made one page with this PR (Integrations page), but the page includes lots of GraphQL proxies and functionality.
