fix(historian-gateway): historize under the historian name, not the mux ref, when HistorianTagname overrides (FU-3)
The continuous-historization recorder conflated two identifiers into one string: the dependency mux fans DependencyValueChanged keyed by the driver FullName (the mux ref), but a value must be historized under the resolved historian name (HistorianTagname override, else FullName). In the common no-override case the two are equal, so it worked; with an override they diverge and the recorder registered mux interest under a key the mux never fans — that tag's values were never captured (and, had they been, would have been written under the mux ref). Carry BOTH identifiers through the seam: a new HistorizedTagRef(MuxRef, HistorianName) record on IHistorizedTagSubscriptionSink. The applier resolves MuxRef = FullName and HistorianName = override-or-FullName. The recorder now keeps a muxRef->historianName map: it registers/filters mux interest by MuxRef but writes the outbox entry (and drains) under HistorianName. The convergence handler re-registers the mux only when the registered key-set changes, so an override-only rename (same FullName) updates the write target without mux churn. Tests: a divergent-override recorder test (interest by mux ref, value written under the override name, never the mux ref) + an override-rename no-churn test; the applier feed tests now assert the full (mux ref, historian name) pairs. Runtime 348/0, OpcUaServer 327/0; 0 warnings. Closes FU-3. Claude-Session: https://claude.ai/code/session_012SDSQ3AcaXqPcBtDESBRii
