feat(opcua): FB-7 surgical DataType/array-shape in-place tag writes

Widen the F10b surgical address-space path so a changed equipment tag whose
only differences are DataType / IsArray / ArrayLength (on top of the existing
Writable / Historizing) is applied IN PLACE on the live node instead of forcing
a full RebuildAddressSpace that drops every client's subscriptions server-wide.

ISurgicalAddressSpaceSink.UpdateTagAttributes gains (dataType, isArray,
arrayLength); the DeferredAddressSpaceSink wrapper forwards all six args (the
prod-inertness seam). OtOpcUaNodeManager swaps DataType + ValueRank +
ArrayDimensions in place, and on a real shape change (a) resets the node to
BadWaitingForInitialData so no stale wrong-typed value is exposed (closes the
prior brief-value-type-mismatch objection) and (b) raises a Part 3
GeneralModelChangeEvent (verb=DataTypeChanged) so model-aware clients re-read
the definition. A Writable/Historizing-only change leaves the shape untouched
(no reset, no model event) — original behaviour preserved byte-for-byte.

AddressSpaceApplier.TagDeltaIsSurgicalEligible adds the three shape fields to
its whitelist; FullName/Name/DriverInstanceId/alarm differences still rebuild.

Tests: new NodeManagerSurgicalShapeUpdateTests boots a real server to prove the
in-place swap + value reset + the no-reset backward-compat path + the model-event
builder; AddressSpaceApplierTests invert the two former DataType/IsArray-rebuild
cases to surgical and assert the shape args land; DeferredAddressSpaceSinkTests
assert the shape args forward. 273/273 OpcUaServer.Tests green; full solution builds.
