将由以下 PR 修复：

> <https://github.com/discourse/discourse/pull/44132>
>
> Previously, deleting a category trashed its About topic but left the first post …live, so \`posts\_count\` stayed at 1 and permanent deletion failed with "This topic still has 0 posts…". Recovering a post in that trashed topic also raised a 500, because post voting's \`is\_post\_voting\_topic?\` dereferenced the nil topic.
> 
> This change trashes the first post along with the topic, repairs existing topics with a post-deploy migration, and makes \`is\_post\_voting\_topic?\` nil-safe.
