Fix: Corregir configuración del modal de resultados

- Cambiar v-model a v-model:open según @nuxt/ui v4.0.0
- Eliminar UCard interno que causaba renderizado permanente
- Usar slots nativos del Modal (#header) en lugar de Card
- Simplificar estilos usando clases de Tailwind estándar
- El modal ahora se mostrará solo cuando showResults sea true
