Domi31tls e967a67052 feat(phase2): Extraction layout-aware multi-colonnes — 322 fuites → 0, -103 FP 
Phase 2 de l'amélioration qualité anonymisation :

1. Extraction multi-colonnes (PyMuPDF layout-aware) :
   - Nouvelle fonction _extract_page_layout_aware() détecte les layouts
     sidebar+corps (typiques des CRH/CRO hospitaliers)
   - Remplace pdfplumber comme extraction primaire (PyMuPDF blocks)
   - Élimine l'entrelacement de texte entre sidebar et corps médical
   - pdfplumber conservé pour les tables et comme fallback

2. Masquage FINESS multiline :
   - Détection "N° Finess\n[...]\n640000162" (label et numéro séparés)
   - Propagation globale du numéro FINESS sur toutes les pages
   - Gestion du format *640000162* (avec astérisques Trackare)

3. Masquage URLs hospitalières (www.ch-xxx.fr)

4. Nettoyage crochets doubles [[PLACEHOLDER]] → [PLACEHOLDER]

Résultats non-régression (30 fichiers audit) :
- Fuites : 322 → 0 (-100%)
- Faux positifs : 113 → 10 (-91%)
- 0 régression fonctionnelle
- OGC 1-59 : 0 fuite soignant, 0 FINESS, 0 lieu de naissance
