Four DB-backed test fixtures still defaulted DefaultServer to
localhost,14330 — missed in the 2026-04-28 Docker migration that moved
SQL Server off this VM onto the shared host 10.100.0.35. With no SQL on
localhost, all 31 DB-backed tests failed with connection timeouts,
which in turn failed the Phase 6 compliance gate (phase-6-all.ps1).
Updated SchemaComplianceFixture, HostStatusPublisherTests,
FleetStatusPollerTests, and AdminServicesIntegrationTests to default to
10.100.0.35,14330 (still overridable via OTOPCUA_CONFIG_TEST_SERVER).
Verified: Configuration.Tests 91 pass, HostStatusPublisher 4 pass,
FleetStatusPoller + AdminServicesIntegration 5 pass — all 31 green.
