Task #242 partial — UnsTab interactive E2E test bodies + harness upgrades (tests Skip-guarded pending blazor.web.js asset plumbing)

Browse Source 
Carries the interactive drag-drop + 409 concurrent-edit test bodies (full Playwright
flows against the real @ondragstart/@ondragover/@ondrop handlers + modal + EF state
round-trip), plus several harness upgrades that push the in-process
WebApplication-based fixture closer to a working Blazor Server circuit. The
interactive tests are marked [Fact(Skip=...)] pending resolution of one remaining
blocker documented in the class docstring.

Harness upgrades (AdminWebAppFactory):
  - Environment set to Development so 500s surface exception stacks (rather than
    the generic error page) during future diagnosis.
  - ContentRootPath pointed at the Admin assembly dir so wwwroot + manifest files
    resolve.
  - Wired SignalR hubs (/hubs/fleet, /hubs/alerts) so ClusterDetail's HubConnection
    negotiation no longer 500s at first render.
  - Services property exposed so tests can open scoped DI contexts against the
    running host (scheduled peer-edit simulation, post-commit state assertion).

Remaining blocker (reason for Skip):
  /_framework/blazor.web.js returns HTTP 200 with a zero-byte body. The asset's
  route is declared in OtOpcUa.Admin.staticwebassets.endpoints.json, but the
  underlying file is shipped by the framework NuGet package
  (Microsoft.AspNetCore.App.Internal.Assets/_framework/blazor.web.js) rather than
  copied into the Admin wwwroot. MapStaticAssets can't resolve it without wiring
  a composite FileProvider or the WebRootPath machinery. Three viable next-session
  approaches listed in the class docstring:
    (a) Composite FileProvider mapping /_framework/* → NuGet cache.
    (b) Subprocess harness spawning real dotnet run of Admin project with an
        InMemory-DB override (closest to production composition).
    (c) MSBuild ItemGroup in the test csproj that copies framework files into the
        test output + ContentRoot=test assembly dir with UseStaticFiles.

Scaffolding smoke test (Admin_host_serves_HTTP_via_Playwright_scaffolding) stays
green unchanged.

Suite state: 1 passed, 2 skipped, 0 failed.
