## ERP-196 — Refonte des blocs de formulaire

Refonte visuelle des blocs répétables des formulaires (clients, fournisseurs, prestataires, transporteurs), alignée sur les blocs « ticket de pesée » : à plat (sans box-shadow), titre de bloc en noir, séparation par filet noir 1px.

### ✅ Blocs Contact
- Box-shadow / fond blanc / padding latéral retirés
- En-tête `flex justify-between` : titre noir (« Contact 1 »…) à gauche, poubelle `button-class="p-0"` à droite
- 4 colonnes, filet `border-b border-black` entre blocs (pas sous le dernier, prop `last`)
- i18n `contact.title` ajouté pour transporteurs / prestataires
- 9 pages câblées (new / edit / consultation des 4 répertoires)

### ✅ Blocs Adresse
- Même traitement (à plat, titre noir, filet sauf dernier)
- i18n `address.title` pour transporteurs / prestataires
- Transporteur : adresse unique → titre « Adresse » (sans numéro)
- 12 pages câblées

### ✅ Bloc Comptabilité
- Bloc **infos** : titre « Informations » + filet bas (uniquement si des RIB suivent)
- Blocs **RIB** : titre « RIB 1 / RIB 2… » + poubelle `p-0`, filet sauf le dernier
- i18n `accounting.infoTitle` (3 modules) + `accounting.ribTitle` (fournisseurs / prestataires)
- 9 pages câblées (clients / fournisseurs / prestataires)

### Vérifications
- Vitest : 44/44 (specs contact + adresse)
- Eslint : clean sur l'ensemble des composants et pages modifiés

### Commits
- `feat : refonte des blocs contact (ERP-196)`
- `feat : refonte des blocs adresse (ERP-196)`
- `feat : refonte du bloc comptabilité (ERP-196)`
