Facia tool update auth endpoints

This changes the proxy endpoints that Facia Tool uses to make calls to both the Content API and Ophan so that it updates the cookie to keep the user logged in.

Before this, if a user opens the facia tool and does not open a collection, the tool can get into a broken state as the requests it was constantly making were not updating the cookie, and when a user finally went into a collection, these requests would be `303` to login.
