985b7aba26 Doc refresh (task #202) — core architecture docs for multi-driver OtOpcUa
Rewrite seven core-architecture docs to match the shipped multi-driver platform.
The v1 single-driver LmxNodeManager framing is replaced with the Core +
capability-interface model — Galaxy is now one driver of seven, and each doc
points at the current class names + source paths.

What changed per file:
- OpcUaServer.md — OtOpcUaServer as StandardServer host; per-driver
  DriverNodeManager + CapabilityInvoker wiring; Config-DB-driven configuration
  (sp_PublishGeneration, DraftRevisionToken, Admin UI); Phase 6.2
  AuthorizationGate integration.
- AddressSpace.md — GenericDriverNodeManager.BuildAddressSpaceAsync walks
  ITagDiscovery.DiscoverAsync and streams DriverAttributeInfo through
  IAddressSpaceBuilder; CapturingBuilder registers alarm-condition sinks;
  per-driver NodeId schemes replace the fixed ns=1;s=ZB root.
- ReadWriteOperations.md — OnReadValue / OnWriteValue dispatch to
  IReadable.ReadAsync / IWritable.WriteAsync through CapabilityInvoker,
  honoring WriteIdempotentAttribute (#143); two-layer authorization
  (WriteAuthzPolicy + Phase 6.2 AuthorizationGate).
- Subscriptions.md — ISubscribable.SubscribeAsync/UnsubscribeAsync is the
  capability surface; STA-thread story is now Galaxy-specific (StaPump inside
  Driver.Galaxy.Host), other drivers are free-threaded.
- AlarmTracking.md — IAlarmSource is optional; AlarmSurfaceInvoker wraps
  Subscribe/Ack/Unsubscribe with fan-out by IPerCallHostResolver and the
  no-retry AlarmAcknowledge pipeline (#143); CapturingBuilder registers sinks
  at build time.
- DataTypeMapping.md — DriverDataType + SecurityClassification are the
  driver-agnostic enums; per-driver mappers (GalaxyProxyDriver inline,
  AbCipDataType, ModbusDriver, etc.); SecurityClassification is metadata only,
  ACL enforcement is at the server layer.
- IncrementalSync.md — IRediscoverable covers backend-change signals;
  sp_ComputeGenerationDiff + DiffViewer drive generation-level change
  detection; IDriver.ReinitializeAsync is the in-process recovery path.

bbd043e97b Add authentication and role-based write access control
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.
