refactor(editor): drop the dead isSearchHighlighted prop

No renderer consumed it. The editor computed it at two call sites and
sub-block passed a hardcoded false into renderLabel's slot for it, so even
the one function that declared a parameter never saw the real value. Its
only live effect was in the memo comparator, where an unconsumed value
changing forced a re-render for nothing.

The name stays in the masking audit's forbidden-inputs list, which guards
against a search signal being wired back into a masking decision.
