Add checkbox to login page to enable moderation tools
Some servers (e.g. Pixelfed) will refuse to log in because it does not recognize the admin scope. This might apply to other servers as well, so make it optional when logging in. Some users who have admin privileges may not feel comfortable giving access to Tokodon right away, so it might function as a safety feature.
It's disabled by default, but I feel bad because it's such a good feature. At the same time, I don't want people attempting to login to their server in vain because of faulty software. Ugh
