back(test): specs validation env + DTO upload (48 -> 59 tests)

- env.validation.spec : config valide/coercion/défauts + rejets (var manquante,
  port hors plage, NODE_ENV inconnu)
- create-api-upload.dto.spec : name requis, emails @ValidateIf (vides OK,
  invalides rejetés), énum convention, MaxLength
- vitest-setup charge reflect-metadata (décorateurs class-validator en test)
