48c54b62 - fix(chat): apply line-clamp to reasoning toggle button on Safari

fix(chat): apply line-clamp to reasoning toggle button on Safari Safari iOS was measuring the collapsed reasoning block at full content height because -webkit-line-clamp on the inner div clips visually but leaves the outer button's layout height unchanged. Moving line-clamp-2 onto the button itself caps its layout height to 2 lines.
