Fix Wisconsin TANF tests and clean up references

- Update all test periods from 2024 to 2025 to match parameter effective dates
- Fix wi_tanf_countable_resources to properly separate vehicle and non-vehicle assets
- Fix wi_tanf_countable_income entity aggregation for EITC
- Delete working_references.md (all citations now embedded in code metadata)

All 44 tests now pass.
