…rf helpers
- WebAuthnOtpDevice: imported from @bitgo/public-types@6.1.0 (id, credentialId, prfSalt?)
- PasskeyAuthResult: stays local (ArrayBuffer not encodable in io-ts)
- WebAuthnProvider: create() -> PublicKeyCredential, get() -> PasskeyAuthResult
- buildEvalByCredential: returns { evalByCredential, credIdToDevice }, skips no-prfSalt devices
- matchDeviceByCredentialId: uses credIdToDevice map, throws retail error message
- export * from './passkey' added to bitgo/index.ts barrel
- unit tests: 8 cases covering happy path, empty list, prfSalt skip, and error message
TICKET: WCN-187
