Use Turbo Frame for Elements Window

[tvdeyen]

What is this pull request for?

Instead of using our own fetch logic on a DIV container we make use of a Turbo Frame.

For now we need to disable the submit buttons inside, because we still use Rails UJS and the remote forms feature that uses js.erb responses from the controller.

Those need to be refactored into Turbo Streams eventually, but this is too much for now.
