feat: add standalone LmxProxy solution, windev VM documentation

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.
