feat(protocol-designer): lazy load air gap/delay FF from local storage

[shlokamin]

Overview

This PR addresses the local storage getItem error we were getting when PD initially loads. The web worker was trying to fetch from local storage because one of the dependencies in its scope was attempting to hit local storage at module load. This also uncovered a test that was not updated, so I updated it to account for extra fields that needed to be added to pre saved step forms.

Changelog

• lazy load air gap/delay FF from local storage

Review requests

Validate that there is no local storage error in the browser console when PD loads
Make sure the default airgap/delay args still show up in the presaved form when the FF is on

Risk assessment

Low

looks good, file saves w/o fields when FF is off, w/ fields when FF is on, no console errors on fresh load after clearing site data
