 FNXC:ModelDropdown 2026-07-15-00:00:
 FN-8212 refines FN-8193 by removing the scroller's top padding. A sticky provider header anchors at the list top, so top padding exposed scrolling model rows in a seam between the fixed header stack and that header. Bottom token spacing preserves the list's trailing rhythm.

+FN-8355 requires the portaled list to remain the touch-scroll owner after filtering and a virtual-keyboard visualViewport reposition. Permit this flex child to shrink below its content height; otherwise the fixed search/header stack can leave its overflow clipped by the dropdown instead of scrollable on iOS and Android.
