fix: add id for activitypub follows (#8689)

* add id for activitypub follows

* fix lint

* fix: follower must be local, followee must be remote

Misskey will only use ActivityPub follow requests for users that are local
and are requesting to follow a remote user. This check is to ensure that
this endpoint can not be used by other services or instances.

* fix: missing import

* render block with id

* fix comment
