feat(api): add attention checker for every 10th question

[hoangsonww]

SUMMARY

This PR adds an attention checker question for every 10th question so we can ensure users are paying close attention to their tasks, by dynamically injecting this question on every 10th question (e.g. 10th, 20th, 30th, etc.)

TEST PLAN

1. Sign up for an account and go to the cases page.
2. Repeatedly answer the first 9 questions. Confirm that you're now at the 10th question.
3. Scroll all the way to the bottom on the questions page, and verify that there is an extra attention checker question.
4. Make sure you can submit the answers for the 10th case normally.
