Subject: [PATCH] :bug: Fix flex layout container
 horizontalSizing/verticalSizing via plugin API (#8555)

Setting horizontalSizing/verticalSizing on a FlexLayoutProxy was
dispatching update-layout-child instead of update-layout, so the
frame's auto-sizing (hug content) was never triggered even though
the getter read back the value correctly.

Also restricts accepted values to #{:fix :auto} (matching shape.cljs)
since frames cannot use :fill, and fixes a copy-paste error that
reported :horizontalPadding instead of :horizontalSizing in error messages.
