refactor(theme-studio): unify the syntax table onto the shared sort

The syntax table had its own sort (srt + a D{} direction map) that read state directly — MAP[kind] for the color column, cell text for elements. The UI and package tables used a separate, more general system (srtTable / cellVal / applyTableSort) that reads the rendered cells. Pointed the syntax headers at srtTable('legbody', col) and deleted srt, so all three tables share one sort.

The mapping is exact: the legtable color cell is a swatch dropdown whose data-val is the hex, which cellVal reads — same key srt sorted on — and the elements cell is text. First-click direction stays ascending. The syntax table sorts on click only; it doesn't opt into the cross-rebuild persistence the UI and package tables get from applyTableSort, which preserves its prior behavior.

Added a #sorttest gate: sort was previously untested, and this collapses two systems into one. It checks the syntax table sorts by color ascending, reverses on a second click, sorts by element name, and that the UI and package tables still sort. The asc/desc pair is self-validating — a no-op sort can't pass both.
