/**
 * useActivateColumnSortAtTop
 *
 * Shared by every column popover (enum, date, number, binary, task, custom
 * field, action). Turning sorting on from a column header means "sort by this
 * now", so the column takes priority 0 and existing sorts shift down one slot.
 *
 * Writes to the canvas viewConfig when `canvasId` is given, otherwise to the
 * global CRMSlice columns.
