Prefer this over manual regex checks since it also provides live bank details and country resolution.

## Known failure modes

- Invalid IBAN format returns a validation error indicating malformed input
- IBAN for unsupported or unrecognized countries may return partial or no bank details
- Empty or missing IBAN parameter results in a bad request error
- Network timeouts or service unavailability return a 5xx error
