9b42b61eb6 Extract historian into a runtime-loaded plugin so hosts without the Wonderware SDK can run with Historian.Enabled=false 
The aahClientManaged SDK is now isolated in ZB.MOM.WW.LmxOpcUa.Historian.Aveva and loaded via HistorianPluginLoader from a Historian/ subfolder only when enabled, removing the SDK from Host's compile-time and deploy-time surface.

95ad9c6866 Resolve 6 of 7 stability review findings and close test coverage gaps 
Fixes P1 StaComThread hang (crash-path faulting via WorkItem queue), P1 subscription
fire-and-forget (block+log or ContinueWith on 5 call sites), P2 continuation point
leak (PurgeExpired on Retrieve/Release), P2 dashboard bind failure (localhost prefix,
bool Start), P3 background loop double-start (task handles + join on stop in 3 files),
and P3 config logging exposure (SqlConnectionStringBuilder password masking). Adds
FakeMxAccessClient fault injection and 12 new tests. Documents required runtime
assemblies in ServiceHosting.md.

a55153d7d5 Add configurable non-transparent OPC UA server redundancy 
Separates ApplicationUri from namespace identity so each instance in a
redundant pair has a unique server URI while sharing the same Galaxy
namespace. Exposes RedundancySupport, ServerUriArray, and dynamic
ServiceLevel through the standard OPC UA server object. ServiceLevel
is computed from role (Primary/Secondary) and runtime health (MXAccess
and DB connectivity). Adds CLI redundancy command, second deployed
service instance, and 31 new tests including paired-server integration.
