feat(commercial) : amélioration et validation stricte des champs date (ERP-148) (#92)

## Contexte
ERP-148 — mise à jour @malio/layer-ui et amélioration des champs date (onglet Information, Client & Fournisseur).

## Changements
- **MalioDate v1.7.10** : le composant expose désormais son état de validité (`@update:valid`) et la saisie brute invalide (`@update:rawValue`).
- **Validation back-autoritaire du format** : `foundedAt` n'accepte plus que l'ISO strict `Y-m-d` (`#[Context]` DateTimeNormalizer) + `collectDenormalizationErrors` sur `Client` et `Supplier`. Toute saisie non-ISO renvoie un **422 porté sur le champ**.
  - Corrige un cas piège : `12/25/2026` (invalide en JJ/MM/AAAA côté front) était auparavant accepté par PHP en M/J/AAAA → 25 décembre. Désormais rejeté.
- **Front** : la saisie invalide est transmise au back ; le message technique de type-error est surchargé par une clé i18n via le **code de violation** (`resolveViolationMessage` / `VIOLATION_MESSAGE_I18N`), affiché inline par `useFormErrors`.
- Réorganisation des utils de formulaire sous `utils/forms/`.

## Tests
- Back : `ClientFoundedAtFormatTest` / `SupplierFoundedAtFormatTest` (dont le cas piège `12/25/2026`).
- Front : résolveur i18n (`api.test.ts`, `useFormErrors.test.ts`) + payloads (`clientEdit`/`supplierEdit` specs).
- Suite Commercial verte ; vérifié bout-en-bout en navigateur (PATCH → 422, erreur inline, submit bloqué).

## Note
Échecs JWT aléatoires connus du hook pre-commit (401/500 sur tests d'auth sans rapport) ; tous verts en isolation.
