Update validateSSN validator to allow for all 0s,1s,...,9s as valid possible values except in cat3 scenarios.

[ADPennington]

Description:

OFA's coding instructions indicate the following for STTs (this instruction is consistent for TANF, SSP, and Tribal TANF for adult and child records):

Social Security Number: Enter the nine-digit Social Security Number (SSN) for the adult. If the family affiliation code is 1 or 2, the state must provide the SSN, unless family affiliation is 2 with no SSN due to immigration status. If the family affiliation code is not 1 or 2, enter 999999999.

This is describing the conditions for a cat 3 error (inconsistency between related data elements in the same record) which has already been implemented, but based on review of error reports for recently submitted data files in prod, TDP is also flagging SSN values like this as cat 2 (out of range) errors.

all 0s,1s,...,9s are possible values for SSN. TDP should only raise cat 3 errors related to SSN.

Priority: Parity

• cat 2 error is not raised when SSN == all 0s, 1s, ..., 9s in Tribal TANF Sections 1 and 2
• Testing Checklist has been run and all tests pass
