Registers a PushOk reply for conversation:create on siteTopic.
convId becomes both conversationId and conv_id in the response,
matching what the backend returns.

replyFor(
topic: siteTopic,
event: 'conversation:create',
result: PushOk({
'conversation': {'conv_id': convId, 'conversationId': convId},
}),
);
}
