Auth via `articlepic` → `categoryarticle` → `resolveCategoryAccess`. Errors: `Image not found`, `Not authorized`.
`contentType` is always `image/avif`. In dashback:
```js
const { buffer, contentType } = await store.pic.getImageByHash(req.user.id, hash);
res.set('Content-Type', contentType).send(buffer);
```
