- metadata_batch, metadata_refresh, reading_status_match, reading_status_push,
download_detection : library_id devient optionnel, la boucle passe côté API
- rebuild (index_jobs.rs), thumbnail_rebuild, thumbnail_regenerate : même logique,
suppression du job unique library_id=NULL au profit d'un job par lib
- Backoffice simplifié : suppression des boucles frontend, les Server Actions
appellent directement l'API sans library_id pour le cas "toutes les librairies"

On rate limit, wait 10 seconds and retry the same series. If the retry
also returns 429, the job stops. Otherwise it continues normally.

Continuing after a 429 is pointless — all subsequent requests will also
fail. The job now returns Err immediately, which sets status='failed' with
a clear message indicating where it stopped.
