Cursor Agentandrmcrackan f806af9632 fix(queue): explain a multi-book download that queues nothing
The multi-book branch of QueueDownloadDecryptAsync returned false with no log
entry and no message whenever UnLiberated() came back empty, so a request
Libation understood and declined looked exactly like a dead button. Callers that
pre-filter with UnLiberated() land here with an empty list, which is the common
way to hit it.

Classify each title that cannot be queued and report the breakdown: already
downloaded, previously failed, absent from the last scan, or a series parent with
no audio of its own. Log it either way; show it only when a person is waiting,
so the automatic post-scan download stays silent.

Fixes #1940
