Overturns the earlier wrong "WCF not served on 2023 R2" conclusion (that was a
test error: wrong port/transport for the reverse tunnel). Corrected: the cert
(TLS) transport + NegotiateAuthentication auth reach the 2023 R2 historian
cross-platform; the 0x501 event connection mode makes CM_EVENT RegisterTags
succeed; yet StartEventQuery returns a 0-row buffer + long-polls over a window
that has events. Registration and window ruled out -> the same server-side
per-connection row gate as gRPC. Event reads stay server-gated over BOTH
transports; not client-fixable. Evidence doc rewritten; gRPC + WCF orchestrator
gating messages corrected.
