feat(schema): module de nettoyage des JSONs pour consommation aval

Le pipeline produit un JSON riche pendant l'exécution (ratios
checkbox, OCR raw, flags _parse_error/_truncated_loop/_crop_recodage,
_source, _elapsed_s…). Utile en audit, mais pollue quand on veut
exposer le résultat à un consommateur aval (Excel, dashboard, API).

pipeline/schema.py :
- SCHEMA_VERSION "2.0"
- clean_dossier(raw) : retourne une copie propre avec structure stable
  (en-tête → codage → GHM/GHS → décisions) et validation ATIH en
  format compact (summary + cross_checks + flags par champ).
- CLEAN_FIELDS_RECUEIL / CLEAN_FIELDS_CONCERTATION_{1,2} / CLEAN_FIELDS_PREUVES
  documentent les champs stables par type de page.
- CLI : `python -m pipeline.schema` → nettoie `output/v2/*.json` vers
  `output/v2_clean/`.

Séparation claire : `output/v2/` reste le JSON raw (audit), `output/v2_clean/`
est la sortie propre et stable pour livrables.
