Subject: [PATCH] feat(issues): register board columns and list scroller for
 scroll mementos

Per-container scroll registration for the MUL-4741 tab session memento:
board columns key by group id (each column's offset restores
independently, the per-column split Linear ships), the list view keys as
"list". Chat and issue-detail already carry the marker.
