fix(books): show read status on the book detail discovery shelf

The series, author and similar endpoints never selected a read status, so
every cover in the detail shelf rendered bare. Attach the requesting user's
status in one bulk lookup per lane, and draw the badge in BookCarousel using
the same icons and placement as the library grid, plus an sr-only label.
BookRepository has no user in scope, so it now returns UnscopedBookRecommendation
and the type system forces the status on where the user exists.

Also adds the untracked scanner overlap repro for issue 1094.

Closes #1163
