Is PM acceptance required? (delete one)

• Yes - don't merge until JIRA issue is accepted!

Reminder: merge main into this branch and get green tests before merging to main

What was done?

• The story calls for us to handle the "SSN not valid for employment" status on a per-filer basis, instead of per-intake. I removed relevant question from the form, removed the field from StateFileAzIntake and used the JSON data directly when determining how many filers are eligible for excise credit

How to test?

• Ideally, this should be tested for six separate cases:
  • non-mfj with valid-for-employment SSN (gets excise credit)
  • non-mfj with not-valid-for-employment SSN (does not get excise credit)
  • mfj with spouse not-valid-for-employment SSN (gets excise credit for one fewer household member)
  • mfj with primary not-valid-for-employment SSN (gets excise credit for one fewer household member)
  • mfj with both not-valid-for-employment SSN (does not get excise credit)
  • mfj with neither not-valid-for-employment SSN (gets excise credit with both filer and spouse included)
• Automated tests have been added that cover these scenarios
