Marc Schier b97fd8d4b5 Fix OPC 10000-21 onboarding interoperability (#4385)
# Description

Fix the four blockers that prevented the OPC 10000-21 onboarding
registrar and client from working end to end:

- generate every `ModelDesign` target independently, including multiple
models in one directory, while preserving stable identifier CSV matching
and cross-model dependencies;
- ship the generated `Opc.Ua.Onboarding` constants, node states,
encodeables, and typed clients from `Opc.Ua.Gds.Common`;
- correct the standard `EncodedTicket` datatype to derive from
`ByteString`;
- align the new 2.0 `OnboardingClient` API with the generated
`ArrayOf<ByteString>` / `ArrayOf<StatusCode>` contract;
- make `BindToTicketStore` fully asynchronous, cancellation-aware, and
assign the declared output slot instead of appending a second output;
- add generated-model, client fallback, server binding, and in-process
end-to-end regressions.

The change also adds `samples/Gds/OnboardingRegistrar`,
`samples/Gds/OnboardingClient`, and `run-onboarding-demo.ps1`. The demo
loads the generated GDS and Onboarding models, restricts ticket
administration to an ephemeral `RegistrarAdmin` user, proves anonymous
access is denied, and completes a secure register/unregister round trip.

The History CI follow-up rejects negative and non-finite
processed-history intervals before provider dispatch and enforces the
buffered aggregate output cap while calculator results are flushed. This
prevents malformed requests from running until the client timeout,
exhausting memory, delaying server teardown, and causing later
alarm-event tests to fail.

## Related Issues

- Fixes #4378
- Unblocks OPCFoundation/UA-.NETStandard-Samples#819
- Tracks the canonical model correction in OPCFoundation/UA-Nodeset#122

## Validation

- Full `net10.0` test projects:
  - `Opc.Ua.SourceGeneration.Core.Tests`: 3803 passed, 8 skipped
  - `Opc.Ua.SourceGeneration.Tests`: 143 passed
  - `Opc.Ua.Gds.Tests`: 1114 passed, 42 skipped
- `Opc.Ua.History.Tests` with the CI coverage settings: 506 passed, 27
skipped
- `HistorianDispatcher` tests: 88 passed on `net10.0`.
- Invalid processed-history interval regressions passed on `net10.0` and
`net48`.
- Focused onboarding/source-generation regressions passed on `net48`.
- `dotnet build UA.slnx -p:CustomTestTarget=net10.0 --no-restore`
succeeded; the reported analyzer warnings are pre-existing in unchanged
XRegistry/WoT files.
- Packed all three GDS packages and verified the packaged
`Opc.Ua.Gds.Common` assembly contains the generated Onboarding model
surface.
- `pwsh samples/Gds/run-onboarding-demo.ps1` verified anonymous denial
and the authenticated secure ticket lifecycle.
