fix: prefer user-renamed label over interior widget store label for promoted widgets

The PromotedWidgetView.label getter read from widgetValueStore first,
returning the interior widget's own name (e.g. "value") instead of the
user's renamed label (e.g. "prompt"). Swap priority so displayName
(from input.label) is checked first.

For legacy canvas, the projected interior BaseWidget reads its own
store label directly, so temporarily override it during draw().

For Vue Node rendering, NodeWidgets.vue fetches widgetState from the
store independently; prefer slotName (which carries the renamed label)
over widgetState.label.

Fixes promoted widget label regression introduced by PR #9896/#9928.
