mejora vista de votación: modal, alineación y auto-reproducción del ganador

- Tarjetas de votación ahora abren el modal de canciones al hacer clic en la imagen/nombre
- Botón "Votar" siempre alineado al fondo independiente del alto de cada tarjeta
- Muestra descripción de la playlist en modo votación
- Emoji de playlist escala proporcionalmente usando container queries (55cqi)
- Al cerrar la votación, reproduce automáticamente la playlist con más votos
