Two pre-emptive cleanups flagged by code review before sub-plan 2
copies the patterns:
1. Sort the internal/audiobooks import after internal/adminjob in
cmd/silo/main.go (alphabetical).
2. Drop the redundant "audiobooks: " prefix from the Enabled() error
wrap; matches how every other top-level service package
(watchstate, scanqueue, metadata, etc.) formats errors.
No behavior change.
