Fix OAuth, LDAP and SAML SSO when regular sign-ups are disabled

Closes #31294

See merge request !10896

The problem is that we often go via a diff object constructed from the diffs
stored in the DB. Those diffs, by definition, don't overflow, so we don't have
access to the 'correct' `real_size` - that is stored on the MR diff object
iself.

Fix typo in discussions doc.

See merge request !10889

which results in Git complaining about untracked files

- To prevent an attacker from enumerating the `/users` API to get a list of all
  the admins.

- Display the `is_admin?` flag wherever we display the `private_token` - at the
  moment, there are two instances:

  - When an admin uses `sudo` to view the `/user` endpoint
  - When logging in using the `/session` endpoint
