front(test): Vitest + premier spec (ErrorService)

- Vitest (cohérent avec le back) pour les tests de logique/services purs ;
  vitest-setup charge @angular/compiler (fallback JIT requis pour importer
  les symboles @angular/* partiellement compilés)
- error.service.spec.ts : 6 cas couvrant toMessage()
- script test -> vitest run (+ test:watch). Tests de composants TestBed =
  plugin Angular dédié, hors périmètre pour l'instant.
