Use a strict action-client mock in this no-op test.

newMockActionGetter allows ActionClientFor, Get, and History with AnyTimes(). A future Migrate change could perform a Helm lookup before returning without failing this test. Use an action getter with no allowed calls, or let the helper disable its default expectations for this test.

minimal, and validate.

In `@internal/operator-controller/applier/boxcutter_test.go` at line 1666, Update
the no-op test around newMockActionGetter to use a strict action-client mock
that permits no calls, or configure the helper to disable its default AnyTimes
expectations. Ensure unexpected ActionClientFor, Get, History, or other lookup
calls fail the test while preserving the existing no-op behavior.
