Drop the filled status chip (bg-warning/text-white etc.) from the
list/board column headers — StatusIcon already carries the semantic
color, so the chip duplicated it on the text background, and the
bg-muted variants were nearly invisible against the muted/40 row
background. Wrap the shared icon + label + count in a new StatusHeading
component used by both list-view and board-column.
Remove the now-unused badgeBg/badgeText fields from STATUS_CONFIG.
