Add Chapter numbers to the book builder component name display
Before the latest model for naming and numbering book builder components (tagging Title styles, non-editable chapter numbers displaying in Wax), the name of Body components displayed a non-editable chapter number before the chapter title. The number was automatically assigned to reflect the order of the component, and automatically updated when components were click-and-dragged into different orders.
In the current model, the automatic chapter numbering based on component order still exists and updates as component order changes, but the chapter number is only visible in Wax, not in the book builder. Based on feedback that Juliana and the other editors sometimes refer to chapters by number rather than name for convenience, the numbers prepending the component title should be added back into the book builder view. This shouldn't change the non-editable chapter numbers that display in Wax at the top of each chapter.
