Migrate off of Instagram Basic Display API

[phette23]

Stopped working as of December 4th: https://developers.facebook.com/blog/post/2024/09/04/update-on-instagram-basic-display-api/

From the descriptions of the two options (Instagram API with either Instagram or Facebook Login) it sounds like Facebook Login is what we need since it has the "get published photos" and "get basic data about other accounts" functions: https://developers.facebook.com/docs/instagram-platform/instagram-api-with-facebook-login

See this page on scraping, too.

To do: delete outdated models (InstagramSettings, InstagramOAuthToken). See django Migration docs and migrations.DeleteModel.
