[52510] Specify intent for every loan in COE form.

[data-doge]

Summary

The COE form was originally designed to accept a singular loan intent, regardless of how many other prior loans a vet specified in the form. We have since learned that each loan should have its own intent. This PR accompanies department-of-veterans-affairs/vets-website#23249, and sends a separate intent for each loan, to LGY.

I am on the benefit decision reviews team (fka benefits team 1), who is currently responsible for the COE form.

This work is behind a feature toggle, and exposed only to a limited number of users taking part in our pilot test sessions.
