fix(supply-quick-add): dropdown not rendering — Portal + fixed position

Корень проблемы: Section рендерится с класcом overflow-hidden (нужен
для скруглений углов) — absolute-позиционированный dropdown
обрезался границей карточки и был не виден совсем.

Решение: dropdown через React createPortal вынесен в document.body,
позиция вычисляется по getBoundingClientRect() input'а на каждый
open + window scroll/resize. position: fixed, z-[100] — выше любого
sticky-header. Outside-click handler теперь учитывает оба контейнера
(input wrap + portal-узел) — клик по элементу dropdown'а больше
не закрывает его как «снаружи».
