Submit the WebAuthn assertion for passkey pairing

Send the WebAuthn assertion produced for the pending challenge (see GET /app/passkey). The assertion must be produced by an authenticator holding the WhatsApp account’s passkey, against WhatsApp’s relying-party ID; the payload format matches PublicKeyCredential.toJSON(). If the assertion is submitted within the 5-minute handoff window, pairing is confirmed automatically; otherwise a confirmation code is issued (PASSKEY_CONFIRMATION websocket event) and must be confirmed via POST /app/passkey/confirm.
