Move auto-delete settings

[ByteHamster]

Description

Users had a hard time understanding that automatic deletion and episode cleanup are two different things. Maybe that is because in German, both got translated to the exact same string. Now both are next to each other and the titles are updated, so that it hopefully causes less confusion.

Closes #4795
