Show and edit embedded monday docs in the files pane

When adding a monday document to a files column of an item it would be nice to see them in the files tab next to the updates.

We want to use them for a more detailed description of our items that should be easily accessible and editable. Quite similar how the deprecated Infoboxes worked. Navigating to the files tab and switching between items is much faster than opening and closing the file for each item.
