Marc Schier 5b9bcedc62 Add OPC UA ISA-95 Common Model and Job Control support (#4089) ...

# Description

Adds first-class support for the OPC UA ISA-95 companion specifications:

- OPC-10030 Common Model.
- OPC-10031-4 Job Control V1.
- OPC-10031-4 Job Control V2.

The change introduces `Opc.Ua.ISA95`, `Opc.Ua.ISA95.Client`, and
`Opc.Ua.ISA95.Server`, together with a NativeAOT-compatible minimal
server sample and comprehensive tests.

## Highlights

- Compiles the three canonical NodeSets and identifier mapping CSV files
through the source generator.
- Adds NodeSet identifier mapping validation, typed method
arguments/results, companion event records, and generated method
argument nodes.
- Provides typed Common Model builders with normative relationships and
an injectable `GeoSpatialLocationType` provider.
- Implements lossless V1/V2 Job Control providers over a shared
version-neutral store, including state paths, status events, comments,
response queries, catalog changes, and cohesive DI registration.
- Adds subtype-aware typed clients, standalone encodeable registration,
`IIsa95ClientFactory`, and V2 status-event streaming.
- Adds the `MinimalIsa95Server` sample, package documentation, and an
ISA-95 guide with conformance and HA guidance.
- Tracks typed RSL/GPOS integration as follow-up issue #4095.

## Validation

- `Opc.Ua.ISA95.Tests`: 137/137 passed on `net10.0` and `net48`.
- Source-generator suites: 81/81 model, 90/90 stack, 3718 passed / 8
skipped core.
- `EventRecordFieldReaders` feedback tests: 6/6 on `net10.0` and
`net48`.
- `EventRecordFieldReaders` changed-method patch coverage: 100% line
coverage (36/36) and 100% branch coverage (22/22).
- `Opc.Ua.ISA95`, `.Client`, and `.Server` build across all configured
target frameworks without new diagnostics.
- Cobertura line coverage: 88.08% model, 90.04% client, 91.19% server.
- NativeAOT sample publishes and passes a live typed V2
Store/status-event validation.
- The ISA-95 NativeAOT smoke test passes in the source-generated native
test executable.
- OPC UA KB NodeSet validation reports zero errors for Common, V1, and
V2.

The broader NativeAOT executable still reports unrelated existing GDS
and complex-type test failures; the ISA-95-specific native test passes.

## Node state generator fixes

Generating method arguments inline for imported nodesets regressed every
model that already emits `InputArguments` / `OutputArguments` child node
factories:

- The inline block ran before the child factories.
`MethodState.CreateOrReplaceInputArguments` keeps the property that was
assigned first, so the child carrying the well-known NodeId was dropped
and a NodeId-less placeholder remained in the address space. This broke
browsing (reference descriptions without a target) and made method
arguments unreachable at their well-known NodeIds.
- The `MethodDeclarationId` fallback keyed on an autogenerated display
name redirected every declared method of the standard address space to
its own NodeId, which made method calls fail.

The inline block is now emitted after the child factories and reduced to
a value assignment when a child factory exists. The value is only
re-emitted when an argument references a namespace other than OPC UA,
because the value of an imported property is the verbatim XML of the
source nodeset whose namespace indices do not survive the import. The
`MethodDeclarationId` fallback is restricted to declarations without a
resolvable NodeId. The generated OPC UA address space is byte-identical
to `master` again.
