feat: AniList reading status integration

- Add full AniList integration: OAuth connect, series linking, push/pull sync
- Push: PLANNING/CURRENT/COMPLETED based on books read vs total_volumes (never auto-complete from owned books alone)
- Pull: update local reading progress from AniList list (per-user)
- Detailed sync/pull reports with per-series status and progress
- Local user selector in settings to scope sync to a specific user
- Rename "AniList" tab/buttons to generic "État de lecture" / "Reading status"
- Make Bédéthèque and AniList badges clickable links on series detail page
- Fix ON CONFLICT error on series link (provider column in PK)
- Migration 0054: fix series_metadata missing columns (authors, publishers, locked_fields, total_volumes, status)
- Align button heights on series detail page; move MarkSeriesReadButton to action row
