add button for creating a list from run form field

This is an initial/draft implementation. Some of the next steps are:
- By default, instead of the modals treating the items as selections from the current history, automatically filter items valid for the list (e.g.: for a list with csv elements, filter out csvs from the history in this list).
- In case nothing can be auto paried for `list:paired`, do not attempt to auto pair by default and simply show all items.
- In case the current history is empty and to make it clearer in general, allow history to be switched from within the modal?
- Allow files to be uploaded (and dropped) directly to either the form field or within the list builder once it is opened.

One thing I have not planned for yet is the rule builder. I can see that for `list` and `list:paired`, we get that from the `props.collectionTypes` in `FormData`. But when would we use the rule builder instead?
