/// Phase 6.4 UnsTab drag-drop E2E smoke (task #199). This PR lands the Playwright +
/// WebApplicationFactory-equivalent scaffolding so future E2E coverage builds on it
/// rather than setting it up from scratch.
///
///
///
/// Prerequisite. Chromium must be installed locally:
/// pwsh tests/ZB.MOM.WW.OtOpcUa.Admin.E2ETests/bin/Debug/net10.0/playwright.ps1 install chromium.
/// When the binary is missing the tests rather than fail hard,
/// so CI pipelines that don't run the install step still report green.
///
///
/// Current scope. The host-reachability smoke below proves the infra works:
/// Kestrel-on-a-free-port, InMemory DbContext swap,
/// bypass, and Playwright-to-real-browser are all exercised. The actual drag-drop
/// interactive assertion is filed as a follow-up (task #242) because
/// Blazor Server interactive render through a test-owned pipeline needs a dedicated
/// diagnosis pass — the scaffolding lands here first so that follow-up can focus on
/// the Blazor-specific wiring instead of rebuilding the harness.
