Quitar swipe entre charts + ventana del brush deslizable (build 80) #31 #32

Feedback TF build 79: fuera el swipe entre gráficas (navegación = chip bar;
el gesto chocaba con scrub/pan/brush). Brush con gesto unificado decidido en
touch-down: cerca de un asa (18pt) redimensiona; en cualquier otro punto
(dentro de la ventana o sobre el historial atenuado) desliza la ventana entera
manteniendo el ancho — seleccionar ene–mar y arrastrar hasta jun–ago. Con
ventanas estrechas las asas solo agarran desde fuera, el interior siempre mueve.
