feat: ajout déduplication des entités extraites

- Déduplication déterministe des identités, adresses, dates, entreprises, signatures et références
- Implémentation dans src/services/ruleNer.ts et src/services/backendApi.ts
- Clés de normalisation: prénom+nom, rue+CP+ville, nom+SIRET, type+valeur
- Test ciblé tests/deduplication.test.ts pour valider la fonctionnalité
- Documentation complète dans docs/deduplication_entites.md
- Correction des tests existants (supertest, extractEntitiesFromText)
- Compilation validée et services opérationnels

+title: Déduplication des entités extraites
+description: Règles et clés de normalisation pour éliminer les doublons d'entités
+---
+
+## Contexte
+
+Afin d'éviter l'affichage et le traitement multiple de la même information, une déduplication déterministe a été ajoutée côté frontend après l'extraction des entités.
+
+## Périmètre
+
+- Identités (personnes)
+- Adresses
+- Dates
+- Entreprises (nom, SIREN, SIRET)
+- Signatures
+- Références (type, valeur)
+
+## Règles de déduplication
+
+- Identités: clé = `lower(trim(firstName))|lower(trim(lastName))`
+- Adresses: clé = `lower(trim(street))|trim(postalCode)|lower(trim(city))|lower(trim(country))`
+- Dates: utilisation d'un `Set` (unicité par valeur exacte)
+- Entreprises: clé = `lower(trim(name))|trim(siren)|trim(siret)`
+- Signatures: utilisation d'un `Set` (unicité par valeur exacte)
+- Références: clé = `lower(trim(type))|lower(trim(value))`
+
+## Points d'intégration
+
+- `src/services/ruleNer.ts`: déduplication appliquée au résultat du NER par règles.
+- `src/services/backendApi.ts`: déduplication appliquée après le mapping de la réponse backend standard.
+
+## Effets de bord
+
+- L'ordre des entités est conservé (première occurrence préservée).
+- Les entrées vides sont normalisées avant comparaison (trim/lowercase) pour limiter les faux doublons.
+
+## Validation
+
+Un test ciblé `tests/deduplication.test.ts` vérifie que des doublons simples (noms/adresses répétés) sont éliminés.
