Add a polymorphic `subject` field that records the subject of the mod action. The subject is the post, user, comment, artist, etc the mod action is for. * The subject for the user ban and unban actions is the user, not the ban itself. * The subject for the user feedback update and deletion actions is the user, not the feedback itself. * The subject for the post undeletion action is the post, not the approval itself. * The subject for the move favorites action is the source post where the favorites were moved from, not the destination post where the favorites were moved to. * The subject for the post permanent delete action is nil, because the post itself is hard deleted. * When a post is permanently deleted, all mod actions related to the post are deleted as well.
