fix(client): surface a Bad per-node HistoryRead status instead of '0 values returned'

DefaultSessionAdapter swallowed a Bad HistoryReadResult.StatusCode (raw: break;
aggregate: skip) so Client.CLI/UI printed an empty result for
BadHistoryOperationUnsupported / BadUserAccessDenied. It now throws a
ServiceResultException naming the node and status; BadNoData stays empty.
