feat(safer): validate files with Safer

we need to check the blockNsfw user setting to determine whether they want to see nsfw content. This current change would always blur if its nsfw, regardless of user setting. Although, we could probably add the settings check to the image-container component, rather than doing it at the parent level every time

-- edit: I now see this specific component was referencing the old textile state. example of new implementation can be found here
components/views/chat/chatbar/upload/preview/item/Item.vue

Thanks @josephmcg for the review, I haven't looked at the front-end side of Safer yet, this was just me working around enabling a user to send a file in chat so I can test the iridium side, since that wasn't fully working at the time of this branch's creation. but I will look into the new implementation you suggested soon. 👍🏻 Thanks again!

If this doesn't break anything I would be in favor of merging it and following up with another UI ticket

[josephmcg]

why switch thumbnail from cid to the blob itself? the utility function only returns a scaled down version in the case of image files. If no thumbnail can be generated, it returns undefined. This has potential to store undefined inside iridium (which I believe breaks things)

[maljuburi]

For the thumbnail, my thought was to not store 2 files ( original image + thumbnail ) in the sync-node . Instead I thought thumbnails should only be a manager/front-end utility that resizes the original image we store in sync-node imo. right?

[maljuburi]

Maybe thumbnail shouldn't be in the attachment all together... I don't know!
I think we should only send the original image to the users (after it gets Safer checked).
And then, the users generate its thumbnail.
