DateTime[] from MxAccess was falling through to ToString() fallback,
producing "System.DateTime[]" instead of actual values. Now converts
each DateTime to UTC ticks and stores in Int64Array.

AppEngine built-in tag is always present and constantly updating (~1s),
making it a more reliable probe than a user-deployed TestChildObject tag.

- MxStatusMapper: maps all 40+ MxStatusDetail codes, MxStatusCategory,
and MxStatusSource to human-readable names and client messages
- OnDataChange: checks MXSTATUS_PROXY.success and overrides quality with
specific OPC UA code when MxAccess reports a failure (e.g., CommFailure,
ConfigError, WaitingForInitialData)
- OnWriteComplete: uses MxStatusMapper.FormatStatus for structured logging
- Write errors: catches COMException separately with HRESULT in message
- Read errors: distinguishes COM, timeout, and generic failures in logging

SubscriptionManager tracked client-to-tag routing but never called
MxAccessClient.SubscribeAsync to create the actual COM subscriptions,
so OnDataChange never fired. Now creates MxAccess subscriptions for
new tags and disposes them when the last client unsubscribes.
All 17 integration tests pass.

Split LmxProxy Host and Client into a self-contained solution under lmxproxy/,
ported from the ScadaBridge monorepo with updated namespaces (ZB.MOM.WW.LmxProxy.*).
Client project (.NET 10) inlines Core/DataEngine dependencies and builds clean.
Host project (.NET Fx 4.8) retains ArchestrA.MXAccess for Windows deployment.
Added windev.md documenting the WW_DEV_VM development environment setup.
