feat(readarr): handle the book details tabs and open the edition details popup

Add BookDetailsHandler, covering the editions, history and manual search
tables, the automatic search, manual download and delete book file prompts,
and tab movement across the book details modal.

Selecting an edition builds the EditionDetailsModal client side from the
already loaded row and pushes the popup block. Readarr has no edition detail
endpoint, so there is no network request and no event to dispatch.

The delete book file prompt is guarded on the book files table being
populated. Unlike Lidarr, where a track row carries its own file id, an
edition carries none and the file id comes from a separate table that can be
empty while editions are present.
