palabras: revertir el piloto del wrapper de bloques (base limpia)

El piloto envolvia cada parrafo en <div data-words-node=block><p>, pero
el unico beneficio neto (drag vertical de raiz) ya esta cubierto por el
`dropZone` del sink, y el borde activo punteado funciona igual sobre el
elemento pelado. paragraphSpec.render vuelve a emitir un <p> plano.

Tests del render del motor en verde otra vez (engine de words 430/430).
palabras verificado en navegador: render, grip, drag y borrado intactos.
