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.

a7576ffb38 Implement LmxOpcUa server — all 6 phases complete 
Full OPC UA server on .NET Framework 4.8 (x86) exposing AVEVA System
Platform Galaxy tags via MXAccess. Mirrors Galaxy object hierarchy as
OPC UA address space, translating contained-name browse paths to
tag-name runtime references.

Components implemented:
- Configuration: AppConfiguration with 4 sections, validator
- Domain: ConnectionState, Quality, Vtq, MxDataTypeMapper, error codes
- MxAccess: StaComThread, MxAccessClient (partial classes), MxProxyAdapter
  using strongly-typed ArchestrA.MxAccess COM interop
- Galaxy Repository: SQL queries (hierarchy, attributes, change detection),
  ChangeDetectionService with auto-rebuild on deploy
- OPC UA Server: LmxNodeManager (CustomNodeManager2), LmxOpcUaServer,
  OpcUaServerHost with programmatic config, SecurityPolicy None
- Status Dashboard: HTTP server with HTML/JSON/health endpoints
- Integration: Full 14-step startup, graceful shutdown, component wiring

175 tests (174 unit + 1 integration), all passing.
