feat(indexing): Lot 4 - Progression temps reel, Full Rebuild, Optimisations

- Ajout migrations DB: index_job_errors, library_monitoring, full_rebuild_type
- API: endpoints progression temps reel (/jobs/:id/stream), active jobs, details
- API: support full_rebuild avec suppression donnees existantes
- Indexer: logs detailles avec timing [SCAN][META][PARSER][BDD]
- Indexer: optimisation parsing PDF (lopdf -> pdfinfo) 235x plus rapide
- Indexer: corrections chemins LIBRARIES_ROOT_PATH pour dev local
- Backoffice: composants JobProgress, JobsIndicator (header), JobsList
- Backoffice: SSE streaming pour progression temps reel
- Backoffice: boutons Index/Index Full sur page libraries
- Backoffice: highlight job apres creation avec redirection
- Fix: parsing volume type i32, sync meilisearch cleanup

Perf: parsing PDF passe de 8.7s a 37ms
Perf: indexation 45 fichiers en ~15s vs plusieurs minutes avant
