make all books public by default (revert visibility gating)

Split the single combined UpdateAIJob call at the end of each async
goroutine into two sequential calls (status first, payload second) so
that a failure writing the large results payload does not silently
prevent the job from being marked done. Added recover() to each
goroutine to catch and log panics. Affects chapter-names, description,
and image-gen handlers.
