Terry Jia 653ee48444 FE-557: fix(painter): responsive label layout + correct resize min-height (#12025)
## Summary

- WidgetPainter: stack label above widget when controls width < 350px,
side-by-side otherwise; labels are always rendered (no longer hidden
when narrow).
- useNodeResize: re-measure the node's intrinsic min content height on
every pointermove instead of capturing it once at drag start, so the
height clamp tracks widgets whose controls reflow taller as width
shrinks (e.g. painter switching to compact layout). Without this, the
node visually sticks at its current height and the user has to release
and grab the corner again to free it.
- Add unit tests for both changes.
