feat(book-requests): link releases to their source page and hold imports for review

Torznab and Newznab read the feed's details page, plugins may send infoUrl, and the
search drops any link that could carry a credential. A grab can ask to be held for
review whatever its score, and the held review shows the file's own edition facts,
its cover and the release page. Torznab guids are now digested like Newznab's.
