DataTableRow's React.memo did not depend on columnVisibility.
TanStack row references stay stable when visible columns change, so the
table body did not refresh after View -> Toggle columns until another
action rebuilt the column definitions.

Capture a visible column id signature (visibleColumnIds) outside the
memo and compare it, matching the existing isSelected snapshot pattern.
All tables that use DataTableRow pick up the fix.
