ui: Migrate to Auth0 as Identity Provider

This change updates the frontend codebase to move away from the Google
login and instead use Auth0 as generic Identity Provider. This allows
users to login with other accounts as well.

Since Auth0 has a free tier, users can experiment themselves with OpenDC
locally without having to pay for the login functionality. The code has
been written so that we should be able to migrate away from Auth0 once
it is not a suitable Identity Provider for OpenDC anymore.
