c76ab8fdee Close all four stability-review 2026-04-13 findings so a failed runtime probe subscription can no longer leave a phantom entry that Tick() flips to Stopped and fans out false BadOutOfService quality across a host's subtree, a silently-failed dashboard bind no longer lets the service advertise a successful start while an operator-visible endpoint is dead, the seven sync-over-async sites in LmxNodeManager (rebuild probe sync, Read, Write, four HistoryRead overrides) can no longer park the OPC UA stack thread indefinitely on a hung backend, and alarm auto-subscribe + transferred-subscription restore no longer race shutdown as untracked fire-and-forget tasks.

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.

41f0e9ec4c Migrate historian from SQL to aahClientManaged SDK and resolve all OPC UA Part 11 gaps 
Replace direct SQL queries against Historian Runtime database with the Wonderware
Historian managed SDK (ArchestrA.HistorianAccess). Add HistoryServerCapabilities node,
AggregateFunctions folder, continuation points, ReadAtTime interpolation, ReturnBounds,
ReadModified rejection, HistoricalDataConfiguration per node, historical event access,
and client-side StandardDeviation aggregate support. Remove screenshot tests.

d9463d6998 Remove static Users auth, use shared QualityMapper for historian, simplify LDAP permission checks 
- Remove ConfigUserAuthenticationProvider and Users property — LDAP is the only auth mechanism
- Fix historian quality mapping to use existing QualityMapper (OPC DA quality bytes, not custom mapping)
- Add AppRoles constants, unify HasWritePermission/HasAlarmAckPermission into shared HasRole helper
- Hoist write permission check out of per-item loop, eliminate redundant _ldapRolesEnabled field
- Update docs (Configuration.md, Security.md, OpcUaServer.md, HistoricalDataAccess.md)
