On mobile, show tabs ("All Players" / "My Rankings") instead of a stacked
layout that buries the queue below a long participant list. On the All Players
list, the button now toggles between Add and Remove so users never need to
switch tabs just to drop someone. Desktop keeps the side-by-side panel layout.
Also renames the feature throughout from "queue builder" to "pre-draft rankings"
and the DraftInfoCard button to "Set Pre-Draft Rankings".
