Accept a call

After obtaining the original SignalingInvitation from OnReceiveNewInvitation, accept it with signalingAccept():

const { data: roomCredentials } = await openimsdk.signalingAccept({
  opUserID: currentUserID,
  invitation,
});

opUserID is the current user performing the accept action. invitation must preserve the original roomID, inviter, invitees, and session type from the received invitation; do not reconstruct it.

When the Promise resolves, data is a SignalingAcceptResult containing roomID, token, and liveURL. Connect to the media room only after obtaining a valid token and roomID. Continue merging remote state through Call events.
