chore: bump version to v0.1.119

Empilée sur ERP-143 (#105).

## Périmètre ERP-144
Onglet **Comptabilité** de l'écran `/providers/new` — gated par permission + blocs RIB conditionnels.

- Champs (`Malio*`) : SIREN / Numéro de compte / Mode de TVA (`/api/tva_modes`) / N° de TVA / Délai (`/api/payment_delays`) / Type de règlement (`/api/payment_types`) / Banque (`/api/banks`).
- **RG-3.07** : Banque visible **et** obligatoire **seulement si** Type = `VIREMENT` (affichage conditionnel + payload `bank` forcé à null sinon).
- **RG-3.08** : blocs RIB (Libellé/BIC/IBAN) affichés et requis si Type = `LCR` ; « + RIB » gated (dernier RIB complet) / Supprimer (modal). À la validation, **POST des RIB AVANT** le PATCH des scalaires (le back valide RG-3.08 sur le PATCH).
- **Gating** : onglet présent uniquement si `technique.providers.accounting.view` ; **éditable** uniquement si `.manage` (sinon lecture seule). Masqué pour Bureau/Commerciale.
- « Valider » → PATCH `/api/providers/{id}` (groupe `provider:write:accounting`) + sous-ressource RIBs (`/providers/{id}/ribs` + `/provider_ribs/{id}`). Erreurs 422 inline (scalaires) et par ligne (RIB).
- `useProviderReferentials.loadAccounting()` (chargé seulement si l'onglet est accessible). Helpers purs `utils/forms/providerAccounting.ts`.
- i18n `technique.providers.form.accounting` + `confirmDelete.rib`.

> NB : les placeholders **Rapports / Échanges** relèvent des écrans Consultation/Modification (ERP-145) — le flux de **création** ne porte que 3 onglets (Contact/Adresse/Comptabilité), conformément à la spec.

## Conformité
- `useApi()` only ; `Malio*` only ; pas de masque email ; aucun texte FR en dur ; pas d'import inter-module (helpers ré-implémentés côté Technique, règle ABSOLUE n°1).

## Vérifications
- Vitest : 454/454 (18 nouveaux : helpers compta RG-3.07/3.08, workflow VIREMENT/LCR, ordre RIB→scalaires, 422 inline + par ligne, lecture seule sans manage).
- ESLint : OK.
- `nuxi typecheck` : 0 erreur sur les fichiers source du ticket.
- Golden path navigateur : page compile, onglet Comptabilité visible (gating accounting.view OK pour admin). Contenu de l'onglet gaté derrière le déverrouillage des 3 onglets (multiselect `Malio` non pilotable en a11y) — couvert par les tests unitaires + typecheck.
