(bug) NSFW properties not getting propagated from media post to activity
`/api/v2/admin/nsfw/<guid>` API call is using the existence (and value) of `entity_guid` field to propagate from activity -> media entity but doesn't go the other way.
It should be using the PropagateProperties object to do this.
Also, this API is calling:
```php
$dispatcher->trigger('search:index', 'all', [
'entity' => $entity,
'immediate' => true,
]);
```
Which is not present in the NSFW PropagateProperties delegate.
