fix(centralui-tests): register stub IBrowseService in SecuredWritesTests harness (PLAN-07 known-issue resolved)

The Secured Writes page embeds NodeBrowserDialog (@inject IBrowseService) for
the OPC UA tag picker; bUnit resolves the injected service at render time, so
three SecuredWritesTests failed with 'no registered service of type
IBrowseService'. Register a Substitute.For<IBrowseService>() singleton in the
fixture (mirrors NodeBrowserDialogSearchTests). Suite now 7/7 green.

-- **3 `CentralUI.Tests / SecuredWritesTests` render tests fail — `IBrowseService` not registered in the page's bUnit harness (PLAN-07 / Secured Writes, NOT PLAN-03).** PLAN-03's final full-solution `dotnet test` surfaced 3 failures in `SecuredWritesTests` (`Operator_SeesSubmitForm`, `Operator_Submit_CallsServiceWithEnteredValues`, `Verifier_OwnSubmission_HasApproveAndRejectDisabled`), all `InvalidOperationException: Cannot provide a value for property 'BrowseService' on type 'NodeBrowserDialog' — no registered service of type 'IBrowseService'`. Root cause: the Secured Writes page (`Components/Pages/Operations/SecuredWrites.razor`) renders `Components/Dialogs/NodeBrowserDialog.razor`, which `@inject`s `IBrowseService`; the test fixture (`SecuredWritesTests`) registers `_service`/`_siteRepo`/`_dialog`/auth but **not** a fake `IBrowseService`, so rendering the child dialog throws. **Confirmed pre-existing and out of PLAN-03 scope** — the failing files were last touched by commits outside the PLAN-03 session (`1a7e7351` page/test, `9cff87fe` dialog), and PLAN-03 never touches Secured Writes / CentralUI. Merged to `main` (`c7a0c922`) with this red present because it is not a regression from this branch. **Owner: PLAN-07** — register a stub `IBrowseService` in the `SecuredWritesTests` `Services` collection before `RenderPage()` (or in the shared bUnit fixture).
