Getting very close to the end!

I think this is good to go unless there is a good binding extension for this scenario. #1323 has this scenario a few different places as well:

There is a list of potential options that should all be their own toggle that come from a datasource. When selected, they should be added to a [String] but when deselected, they should be removed from the [String].

Also, quirks:

1. I am getting the media libraries from a .getLibraries call on the ServerUserAdminViewModel. I did this because MediaViewModel filters to only compatible libraries and for this instance I need all types. Should I make this it's own viewModel?
2. I combined Media Access & Media Deletion into the same 'Media Access' view. Do we want these separated? I've already broken the mold from jellyfin-web by not including deletion into [iOS] Admin Dashboard - User Permissions #1313 and IMO Media Access & Media Deletion belong in the same spot but I'm game to change it if it makes more sense elsewhere.
