fix: reverse order of api_key for bg task (#13826)
# Pull Request Template

## Description

we were getting 403, 401 errors on `translate_query` on langfuse and
sentry
This happened because, we use the customer's openai key if they have
BYOK
But translation is something they never opt in so we should not use
their quota for it.
This PR addresses the issue.
