Joseph Doherty 49644fc7fd test(fixtures): migrate integration-test fixture defaults to 10.100.0.35
CLAUDE.md "Docker Workflow" claims (per the 2026-04-28 migration note)
that all fixture-class default endpoints were rewritten to target the
shared Docker host at 10.100.0.35. Audit during today's e2e run showed
the claim was incomplete — five fixture classes still defaulted to
localhost / 127.0.0.1, causing every fixture-touching integration test
to skip with "endpoint unreachable" on a fresh box that hadn't set
the override env vars.

Files corrected:

  - tests/.../Modbus.IntegrationTests/ModbusSimulatorFixture.cs
      DefaultEndpoint: localhost:5020 → 10.100.0.35:5020
  - tests/.../S7.IntegrationTests/Snap7ServerFixture.cs
      DefaultEndpoint: localhost:1102 → 10.100.0.35:1102
  - tests/.../OpcUaClient.IntegrationTests/OpcPlcFixture.cs
      DefaultEndpoint: opc.tcp://localhost:50000 → opc.tcp://10.100.0.35:50000
  - tests/.../AbCip.IntegrationTests/AbServerFixture.cs
      Host default + ResolveHost fallback: 127.0.0.1 → 10.100.0.35
  - tests/.../AbLegacy.IntegrationTests/AbLegacyServerFixture.cs
      Host default + ResolveEndpoint fallback: 127.0.0.1 → 10.100.0.35

XML doc comments referencing the old localhost defaults were updated in
the same pass so the class-summary documentation matches the actual
default. The override-via-env-var mechanism (MODBUS_SIM_ENDPOINT,
AB_SERVER_ENDPOINT, AB_LEGACY_ENDPOINT, S7_SIM_ENDPOINT,
OPCUA_SIM_ENDPOINT) is unchanged — pointing at a real PLC or a
locally-running container still works exactly as before.

Verification:
  - Solution-wide dotnet build: 0 errors.
  - S7.IntegrationTests: 3/3 pass without env-var override.
  - OpcUaClient.IntegrationTests: 3/3 pass without env-var override.
  - Modbus.IntegrationTests: 4/38 (same as the env-var-override run —
    the 2 failures + 32 skips are pre-existing fixture-profile
    mismatches unrelated to this fix).
  - AbCip.IntegrationTests / AbLegacy.IntegrationTests: same results
    as the env-var-override run.
