test(apis): ajouter tests unitaires ApisService + fix upload nouvelle version

- 21 nouveaux tests couvrant create, findOneOrThrow, remove,
  findVersionsOf, setCurrent et regenerate (pattern vi.fn() sans NestJS TestingModule)
- apis.service.ts : ConflictException sur doublon de version (name+convention+version)
- upload.component.ts : verrouillage convention/name/type lors d'une nouvelle
  version, bannière d'info, alerte et blocage si version déjà existante
