fix(navbar): el menú Departamentos no se cierra al mover el cursor hacia él

El panel del mega-menu tenía mt-1 respecto al botón -- como es
position:absolute no suma a la altura del contenedor que escucha
mouseenter/mouseleave, así que ese margen quedaba como una franja
muerta: mover el cursor del botón hacia el panel disparaba
mouseleave a mitad de camino y cerraba el menú antes de poder hacer
clic en una categoría (reportado en vivo).

Se elimina el gap (mt-1) y se agrega un delay de 200ms antes de cerrar,
cancelable si el cursor vuelve a entrar, como margen extra para
movimientos rápidos o en diagonal cerca del borde.
