Description

Right now, Front end applies validations and formatting to the Tax ID that should be applied originally form the llm side.
Exclude full Tax IDs/SSNs from application update logs. Format logs to a boolean (e.g., tax_id_available: true) instead of displaying the raw value.
If there are hyphens present in the id, we should be a be able to tell which type it is:
- EIN format: XX-XXXXXXX → 2 digits, hyphen, 7 digits
- SSN format: XXX-XX-XXXX → 3 digits, hyphen, 2 digits, hyphen, 4 digits
If hyphens are missing, use context to differentiate the type:
- EIN: Triggered by business entities, IRS notices, merchant account, or LLC registration.
- SSN: Triggered by individual persons, W-2s, 1040s, or payroll files.
