DraftModeUIDropDownScreen<ItemType> class

Shared picker content surface used by DraftModeUIDropDown.

The screen owns only the selectable list presentation. It intentionally stays separate from the inline field and route-push logic so each file has a single responsibility inside the drop-down feature. iOS presents this as a pushed page, while Android reuses the same list semantics inside a bottom sheet.
