Støtte for flere bibs per bilde, EXIF-metadata og zoom i gjennomgang

- OCR: ny read_all_bibs() returnerer alle unike startnumre (≥2 sifre) per bilde
- Ingest: oppretter én passering per bib (ikke bare beste), ingen bib → needs_review
- image_tagger.py: skriv/les bib-metadata som JSON i EXIF UserComment (piexif)
- Ingest + resolve: tagger bildefilen med bibs automatisk og ved manuell bekreftelse
- API: POST /api/passages/{id}/reanalyze — re-kjør OCR på eksisterende bilde
- API: POST /api/passages/{id}/resolve oppdaterer nå EXIF med bekreftet bib
- races: ny kolonne bib_filter_enabled (med automatisk migrering) + per-løp toggle
- ReviewPage: Re-analyser-knapp og klikk-for-zoom med scroll/drag
