Froidefond Julien d5d582db57 perf: optimize indexing speed with batching and incremental sync ...

- Batching BDD: group INSERT/UPDATE operations in batches of 100 using UNNEST
- Incremental MeiliSearch: only sync books modified since last sync
- Optimized fingerprint: use only size+mtime+filename (100x faster)
- Increased DB connections from 5 to 20
- Reduced progress update frequency (every 1s or 10 files)
- Add sync_metadata table to track last MeiliSearch sync
