Linter/formatter pass across the full codebase. Restores required partial
keyword on AXAML code-behind classes that the formatter incorrectly removed.

P1: Wire OPC UA monitored items to MXAccess subscriptions
- Override OnCreateMonitoredItemsComplete/OnDeleteMonitoredItemsComplete
in LmxNodeManager to trigger ref-counted SubscribeTag/UnsubscribeTag
- Clients subscribing to tags now start live MXAccess data pushes
P1: Write timeout now returns false instead of true
- Previously a missing OnWriteComplete callback was treated as success
- Now correctly reports failure so OPC UA clients see the error
P1: Auto-reconnect retries from Error state (not just Disconnected)
- Monitor loop now checks both Disconnected and Error states
- Prevents permanent outages after a single failed reconnect attempt
P2: Topological sort on hierarchy before building address space
- Parents guaranteed to appear before children regardless of input order
- Prevents misplaced nodes when SQL returns unsorted results
P3: Skip redundant first-poll rebuild on startup
- ChangeDetectionService accepts initial deploy time from OpcUaService
- First poll only triggers rebuild if deploy time is actually unknown
- Eliminates duplicate DB fetch and address space rebuild at startup
All 212 tests pass (205 unit + 7 integration).

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.
