This patch updates the batch progress update endpoint to respond with a
`400 Bad Request` instead of a `500 Internal Server Error` if a user
sends an invalid request with no body. This is a user error after all.

When using accessibility tools like screen magnifiers, dynamic screen
content can be quite problematic. In particular content, which only
appears if you interact with elements somewhere else on the screen. That
is the case, for example, with the current implementation of tooltips
used by audiobookshelf.
This patch provides a slight adjustment, keeping the tooltips open if
you hover over them. This allows users to have better access to the
content.
Starting to use audiobookshelf, the function of some buttons weren't
very clear to me and while some buttons have tooltips, others have not.
This patch adds some additional tooltips to the user interface,
further explaining some of the functionality.
