Any book in the public/books folder will be added to the database when you run the books:scan command. If a book already exists, it will be skipped.
Adding books to the public/books/consume will list them in the /books/new/consume/files page.
This is useful when you want to add books to the library but don't want to add them to the database yet or to mount a folder where books might arrive later (Maybe like a download folder 🫢).
When books are added to the database, their "verified" status is set to false and a link to all unverified books is available in the menu.
