test(grpc): multi-group ext-prop golden + ConnStatus + tightened write read-back

- WcfTagExtendedPropertyProtocolTests: add a multi-group golden test mirroring the live capture (one group per property + uint16 flags trailer) that the old parser failed; correct the synthetic builder to the uint16-flags trailer. - HistorianGrpcIntegrationTests: add GetConnectionStatusAsync_OverGrpc_ReportsConnected (plan #5); tighten the write-lifecycle read-back to a hard assert now that the parser is fixed; make sandbox cleanup generous best-effort (rename is async + the browse view is eventually consistent, so a hard absence assert was racy).
