fix(centralui)+test(centralui): Low-wave integration — T12 Topology race fixture gains T13's IStaleInstanceProbe dependency; T11 sandbox-run continuation skips StateHasChanged after Dispose

Cross-task regression caught by the combined sweep: TopologyLiveUpdatesTimerDisposeRaceTests
(T12) builds a real DeploymentService, whose constructor grew an IStaleInstanceProbe
parameter in T13 (P7-6 up-to-date pre-filter) — 4 DI-resolution failures on the
integration branch that neither task saw in isolation. Registered a substitute, matching
TopologyPageTests.

Bundle review Minor: ApiMethodForm/SharedScriptForm copied TemplateScriptDialog's sandbox
pattern exactly, whose finally re-renders unconditionally; the plan asked the continuation
to be guarded on disposal, so a _disposed flag now suppresses the post-cancel
StateHasChanged (the reference dialog keeps its original shape — out of T11's scope).
