Extract historian into a runtime-loaded plugin so hosts without the Wonderware SDK can run with Historian.Enabled=false

Browse Source 
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.

`LmxOpcUaServer` inherits from the OPC Foundation `StandardServer` base class and overrides two methods:
- **`CreateMasterNodeManager`** -- Instantiates `LmxNodeManager` with the Galaxy namespace URI, the `IMxAccessClient` for runtime I/O, performance metrics, and an optional `HistorianDataSource`. The node manager is wrapped in a `MasterNodeManager` with no additional core node managers.
- **`CreateMasterNodeManager`** -- Instantiates `LmxNodeManager` with the Galaxy namespace URI, the `IMxAccessClient` for runtime I/O, performance metrics, and an optional `IHistorianDataSource` (supplied by the runtime-loaded historian plugin, see [Historical Data Access](HistoricalDataAccess.md)). The node manager is wrapped in a `MasterNodeManager` with no additional core node managers.
- **`OnServerStarted`** -- Configures redundancy, history capabilities, and server capabilities at startup. Called after the server is fully initialized.
- **`LoadServerProperties`** -- Returns server metadata: manufacturer `ZB MOM`, product `LmxOpcUa Server`, and the assembly version as the software version.
