allowDeviceCredentials property
Android/iOS/macOS Whether to allow device credentials (PIN/pattern/passcode)
as a fallback for biometric authentication.
When true:
- Android: Shows "Use PIN" option after biometric failure
- iOS/macOS: Uses .deviceOwnerAuthentication policy
- Windows: Not applicable (Windows Hello handles fallback internally)
Default: false (biometric-only authentication)
