Full reference dialog for {{path}} / legacy $var interpolation — every
namespace path and family the template engine and the legacy resolver
accept (src/vars/catalog.rs, mirrored by GET /api/vars), plus live
preview values when a trace is available for the selected node.
Opened from the NodeInspector header's "Context vars" button and from the
VarInput popover footer's "Context vars reference" link (both wire the
same onOpenLegend callback back to this dialog's open state).
