Replace direct SQL queries against Historian Runtime database with the Wonderware
Historian managed SDK (ArchestrA.HistorianAccess). Add HistoryServerCapabilities node,
AggregateFunctions folder, continuation points, ReadAtTime interpolation, ReturnBounds,
ReadModified rejection, HistoricalDataConfiguration per node, historical event access,
and client-side StandardDeviation aggregate support. Remove screenshot tests.

Linter/formatter pass across the full codebase. Restores required partial

Separates ApplicationUri from namespace identity so each instance in a
redundant pair has a unique server URI while sharing the same Galaxy
namespace. Exposes RedundancySupport, ServerUriArray, and dynamic
ServiceLevel through the standard OPC UA server object. ServiceLevel
is computed from role (Primary/Secondary) and runtime health (MXAccess
and DB connectivity). Adds CLI redundancy command, second deployed
service instance, and 31 new tests including paired-server integration.

Adds Security section to appsettings.json with configurable OPC UA
transport profiles (None, Basic256Sha256-Sign, Basic256Sha256-SignAndEncrypt),
certificate policy settings, and a configurable BindAddress for the
OPC UA endpoint. Defaults preserve backward compatibility.

When GalaxyRepository.ExtendedAttributes is true, uses the extended
attributes query that includes both primitive (system) and dynamic
(user-defined) attributes. Default is false (dynamic only, preserving
existing behavior). Extended mode returns ~564 attributes vs ~48.
Adds PrimitiveName and AttributeSource fields to GalaxyAttributeInfo.
Includes 5 new unit tests and 6 new integration tests covering both
standard and extended attribute modes.

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.
