For the Files screen, I have not made any changes on purpose. For the
Recents screen, we now display the Book title and author. If it is a
file with no epub metadata like txt or md, we display the file name
without the file extension.

Did you use AI tools to help write this code? _**< YES  >**_

Although I went trough all the code manually and made changes as well,
please be aware the majority of the code is AI generated.
