Fix iOS signing: archive without signing, sign during export (#5673)

- Archive step now skips signing (CODE_SIGN_IDENTITY="-")
- This avoids "UnityFramework does not support provisioning profiles" error
- Export step handles all signing with proper certificate and profile
- Added signingCertificate to export options
