Update rules for when book components can be moved in TOC
We have two ways to move book components:
- Manually (always for components in Front and Back, and only when this setting is chosen for chapters)
- Via the "Move to" button (only applicable ton books with parts)
But book components should only be moved once we have the converted file, because their placement is read from the
content-type. I have updated the rules for each book component status in the status/actions spreadsheet here.
