new-style citations visible in full wax editor

This is a partial solution to #1402 (closed). This makes new-style citations visible in the full wax editor. They are currently read-only – so clicking on them does not open the modal.

In the future, we may make it so that clicking a citation in the full wax editor opens the modal to the edit pane – so the author can make changes – but when saving from this mode, it should add a flag to the node saying that it has been touched by an author, and production should check it.

This MR is reduced and only protects against data loss – as it stands, if you parsed a bunch of citations and then went into the full wax editor, the citations would be changed back into regular paragraphs. This lets them keep their content.
