chore: bump version to v0.1.120

Empilée sur ERP-144 (#106).

## Périmètre ERP-145
Écrans **Consultation** (lecture seule) et **Modification** (édition par onglet), peuplés depuis la **seule** réponse `GET /api/providers/{id}` (embed contacts/adresses/ribs + refs comptables — pas de N+1).

### Consultation — `pages/providers/[id]/index.vue` (`/providers/{id}`)
- Ouverture par défaut sur **Contacts** ; tous champs readonly ; onglets **Contacts · Adresse · Rapports · Échanges · Comptabilité** (navigation libre). Rapports/Échanges = placeholders « À venir ».
- Flèche retour → répertoire. Bouton **Modifier** (si `manage` OU `accounting.manage`). Bouton **Archiver** (Admin seul, `archive`) → modal → PATCH `{isArchived:true}` ; **Restaurer** si archivé.
- Comptabilité visible seulement si `accounting.view` ; banque/RIB affichés selon le type de règlement (VIREMENT/LCR).

### Modification — `pages/providers/[id]/edit.vue` (`/providers/{id}/edit`)
- Pré-rempli ; **bloc principal éditable** (Nom/Catégories/Sites, PATCH `provider:write:main` via `updateMain`) ; onglets Contact/Adresse/Comptabilité en **navigation libre**, PATCH partiel par onglet (réutilise `useProviderForm` en `editMode`).
- Onglets sans permission `manage` / `accounting.manage` restent **readonly** (pas de bouton Valider / suppression). Accès réservé à `manage` OU `accounting.manage`.

### Composables / helpers
- **`useProvider(id)`** : charge le détail (ld+json) + archive/restore (PATCH isArchived seul, puis rechargement).
- **`useProviderForm`** étendu : `updateMain()` (PATCH principal en édition) + `editMode` (completeTab ne verrouille/avance plus).
- **`providerDetail.ts`** : mapping embed → brouillons + options role-indépendantes (libellés depuis l'embed) + règles d'actions (Modifier/Archiver/Restaurer).

## Conformité
- `useApi()` only ; `Malio*` only ; `usePermissions()` pour boutons/onglets ; aucun texte FR en dur ; pas d'import inter-module (règle ABSOLUE n°1).

## Vérifications
- Vitest : 470/470 (16 nouveaux : mapping détail, actions par permission, updateMain + editMode).
- ESLint : OK · `nuxi typecheck` : 0 erreur sur les fichiers source du ticket.
- Golden path navigateur : **Consultation** (ACME) — bloc principal readonly + libellés catégories/sites résolus depuis l'embed, 5 onglets, Modifier+Archiver visibles (admin), Comptabilité readonly. **Modification** — bloc principal éditable pré-rempli (Site « 86 17 »), 3 onglets navigation libre, onglet Contact pré-rempli.
