john-okeefe ed4a8bd171 fix: expect 422 for invalid ISBN updates ...

Test "Update with invalid ISBN rejects" should expect:
- 422 Unprocessable Entity status (not 200 OK)
- ISBN field should be empty/nil in response (not normalized value)

Invalid ISBN with trailing hyphens cannot be normalized to valid ISBN-13.
