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.
Marks the PLAN-07 'Post-plan known issues' entry and the 00-MASTER-TRACKER
registry cross-reference RESOLVED.
