fix(runtime): set Static yoga node to display:none in dynamic layout

Static content is rendered via paintIsolated (separate channel), but its
yoga node was still participating in the dynamic frame layout calculation,
adding blank lines equal to the Static content height between the last
Static item and the dynamic content below.

Setting display:none on the Static yoga node removes it from the dynamic
layout. paintIsolated is unaffected — it reparents children into a
temporary yoga tree.
