Replace static user list with GLAuth LDAP authentication. Group
membership (ReadOnly, ReadWrite, AlarmAck) maps to granular OPC UA
permissions for write and alarm-ack operations. Anonymous can still
browse and read but not write.

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.

Implements configurable user authentication (anonymous + username/password)
with pluggable credential provider (IUserAuthenticationProvider). Anonymous
writes can be disabled via AnonymousCanWrite setting while reads remain
open. Adds -U/-P flags to all CLI commands for authenticated sessions.

Both features now default to disabled and require explicit opt-in via
OpcUa.AlarmTrackingEnabled and Historian.Enabled in appsettings.json,
preventing errors in environments without a Historian database or alarm setup.

Wire Galaxy security_classification to OPC UA AccessLevel (ReadOnly for SecuredWrite/VerifiedWrite/ViewOnly).
Use deployed package chain for attribute queries to exclude undeployed attributes.
Group primitive attributes under their parent variable node (merged Variable+Object).
Add is_historized and is_alarm detection via HistoryExtension/AlarmExtension primitives.
Implement OPC UA HistoryRead backed by Wonderware Historian Runtime database.
Implement AlarmConditionState nodes driven by InAlarm with condition refresh support.
Add historyread and alarms CLI commands for testing.

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.
