Applicant birth date format breaks applicant info view

[ghost]

Describe the bug
The paragraph tag displaying an applicant's birth date breaks rendering entirely.

To Reproduce
Scroll down to the 13th or 14th entry in the applicant list sidebar and choose one of them. Note everything explodes.

Action items

• We shouldn't just be displaying a raw Date object for an applicant. Rather, we should be getting a formatted date string so it's readable.
• Look through the MDN docs for Date and find a way to format the object in the best way possible. We may need to create a new Date and pass in the applicant's birth date as a param to generate the object. Then, we should call some method to format the string. This may be done inline with the HTML or as a helper function to make it cleaner.
