Better stop repeating UX

Currently it's not obvious how to stop a post repeating. It should be.

There are two ways to stop a post repeating currently:

1. Edit the original post and set it to not repeat.
2. Delete the next scheduled post so that the repeat cycle is broken.

1 should really be the only intentional way, but needs to be made more obvious as a users natural inclination is to edit the current post or the next scheduled post rather than the original.

2 is almost a bug as it's not clear that the users intention was that the repeating should be canceled just because they deleted the next scheduled post, maybe they just wanted to skip that week for example...

El issue no nombra archivos ni tests; empieza reproduciendo las dos formas documentadas de detener una publicación repetitiva en el plugin de WordPress y siguiendo los flujos relacionados de edición y programación de publicaciones. Se considera terminado cuando la ruta de cancelación intencional es evidente para los usuarios y eliminar una publicación programada no cancela inesperadamente las repeticiones futuras, con el comportamiento cubierto por un test adecuado o una verificación documentada.
