feat(export): mejora en el selector de destino y manejo de exportaciones

Se actualiza el componente ExportDropdown para incluir un selector de destino que permite elegir entre diferentes perfiles de exportación, incluyendo la opción de ZIP. Se mejora la lógica de descarga y se ajusta el componente SwordProfileSelect para manejar la selección de perfiles de exportación. Además, se realizan cambios en la página Dashboard para integrar el nuevo sistema de exportación.
