refactor: rename fields in upload torrent response

to match latest changes in the database. From:

```json
{
    "data": {
        "torrent_id": 12,
        "info_hash": "c01f910ff0cc2a1b8c7a1f6ab948377604d8c464",
        "original_info_hash": "dc0c6be689b28696319263ef27f9df4da8ded0a2"
    }
}
```

To:

```
{
    "data": {
        "torrent_id": 12,
        "canonical_info_hash": "c01f910ff0cc2a1b8c7a1f6ab948377604d8c464",
        "info_hash": "dc0c6be689b28696319263ef27f9df4da8ded0a2"
    }
}
```
