Support /authorize_interaction so that you can type elk.zone into the box for following

[pandaninjas]

When someone is on Mastodon, clicking the follow button while logged out brings you to a box that looks like the following



Typing elk.zone into the box and clicking "Take me home" brings you to https://elk.zone/authorize_interaction?uri=<original_uri>, e.g. https://elk.zone/authorize_interaction?uri=https%3A%2F%2Finfosec.exchange%2Fusers%2Fjerry.


The feature I am proposing is that elk.zone supports this type of interaction so that when clicking on "Take me home" with elk.zone, it will follow the account.

I think this is a nice-to-have feature.

Regarding the following behavior, I think it's safer to avoid directly following and just showing the account profile when accessing https://elk.zone/authorize_iteraction. That can prevent users from clicking a malicious URL and unintentionally following bad accounts (for example, someone might send a link to https://elk.zone/authorize_interaction?url=https://mastodon.social/users/bad_actor).

For notes, Mastodon implements this /authorize_interaction URL as their web UI feature (not as API) here: https://github.com/mastodon/mastodon/blob/main/app/controllers/authorize_interactions_controller.rb and it seems to simply redirect to corresponding pages depending on whether the url value is post or account.
