Release #0402

Swap to Intercom Chat: Prep for swapping the site chat to use Intercom
🪲 BugFix: Null EV Audit Logs: Fixed an issue where downloads would fail if an I-9 had an EV case with null audit logs (older cases, draft, etc)
Font Size on PDFs: We adjusted the auto font size to accomodate longer names on PDFs like the I-9, W4, etc.
🪲 BugFix: Form I-9 Instructions: We added a popup to allow for staff to open the Form I-9 instructions without being redirected to USCIS
Additional performance enhancements and cleanup tasks
