A node's Condition/prompt preview resolved ${{name}} placeholders with a
single-pass string replace, so a runtime value got duplicated wherever the
same placeholder repeated in the source text (e.g. a Conditional's
${{x}} != null && ${{x}}.contains(...) pattern) and long/verbose values were
dumped inline unbounded. Reuse the existing template-placeholder machinery
(already used for HumanDecisionBlock/HumanInteractionBlock text) instead: a
new "template" field type on the settings dialog renders each placeholder as
its own expandable segment.
