feat(readarr): toggle book monitoring and expose the command on the CLI

The PUT body round-trips through serde_json::Value rather than the typed
Book, so the fields Readarr returns but Book does not declare survive the
toggle instead of being silently dropped. BOOK_JSON now carries a few of
those undeclared fields so a regression to a typed round-trip fails the
tests rather than passing unnoticed.
