Modal closes when clicking outside

[CollinWoo]

Summary

This pull request allows users to close a modal simply by clicking outside of the modal box.

• modal closes once user clicks outside

Test Plan

I tested the modal by running the Carriage application locally, opening various modals, and then clicking on various positions surrounding the outside of the modal to see if the modal closes. A video demonstrating the correct behavior is shown below:

Notes

• For multi-step modals, clicking outside the modal for any step will close the modal. When the modal is opened again, it will revert to the first step. This may be annoying if someone accidentally clicks outside of a modal.
