fix(tables): send only the layout keys an action changes

Pin, reorder, and insert-column each shipped a full columnWidths snapshot
they never modified. Both sinks merge at top-level key granularity, so an
earlier-issued patch landing after a concurrent resize replaced the newer
width map with its stale copy.

Resize, auto-resize, and delete-column still send columnWidths — those
genuinely change it.
