Motivating issue:

```shell
❯ http get 'http://localhost:3000/api/embed/dashboard/eyJhbGciOiJIUzI1NiJ9.eyJyZXNvdXJjZSI6eyJkYXNoYm9hcmQiOjEyfSwicGFyYW1zIjp7fX0.QZ-tEWpgJeSMUuaPfuH6_VQwM2yXNMcuureWCtHsszU/dashcard/162/card/124' x-metabase-locale:fr -pb | jq '.data|.cols|map(.display_name)'
[
  "State",
  "Count"
]
```

I'm running a query that has aggregated columns and it is returning the
untranslated. Note that these are computed and dynamically given a
display name.

```clojure
(case tag
  :count     (i18n/tru "Count")
  :cum-count (i18n/tru "Cumulative count"))
```

The problem is that we run embedding things as admin. And that gets the
current user, which in embed and public spaces is nil, and so binds a
nil to user-locale, which defaults to english when translating.

After:

```
❯ http get 'http://localhost:3000/api/embed/dashboard/eyJhbGciOiJIUzI1NiJ9.eyJyZXNvdXJjZSI6eyJkYXNoYm9hcmQiOjEyfSwicGFyYW1zIjp7fX0.QZ-tEWpgJeSMUuaPfuH6_VQwM2yXNMcuureWCtHsszU/dashcard/162/card/124' x-metabase-locale:fr -pb | jq '.data|.cols|map(.display_name)'
[
  "State",
  "Nombre de lignes"
]

❯ http get 'http://localhost:3000/api/embed/dashboard/eyJhbGciOiJIUzI1NiJ9.eyJyZXNvdXJjZSI6eyJkYXNoYm9hcmQiOjEyfSwicGFyYW1zIjp7fX0.QZ-tEWpgJeSMUuaPfuH6_VQwM2yXNMcuureWCtHsszU/dashcard/162/card/124' x-metabase-locale:zh -pb | jq '.data|.cols|map(.display_name)'
[
  "State",
  "行数"
]

❯ http get 'http://localhost:3000/api/embed/dashboard/eyJhbGciOiJIUzI1NiJ9.eyJyZXNvdXJjZSI6eyJkYXNoYm9hcmQiOjEyfSwicGFyYW1zIjp7fX0.QZ-tEWpgJeSMUuaPfuH6_VQwM2yXNMcuureWCtHsszU/dashcard/162/card/124

' x-metabase-locale:es -pb | jq '.data|.cols|map(.display_name)'
[
  "State",
  "Contar"
]
```

This is fetching a dashboard's card which is a query of orders grouped
by created at month, sum of total.
