Fix four statute-first benefit bugs: MO TANF rounding, SNAP GU/VI limits, HI CCAP TANF income, SSI food ISM date

+Follow the rules on four benefit calculations: Missouri TANF payments are lowered to the whole dollar (13 CSR 40-2.310(14)); SNAP income limits in Guam and the Virgin Islands use the contiguous-state poverty guidelines (7 CFR 273.9(a)); Hawaii CCAP counts Hawaii TANF payments from August 6, 2021 (HAR 17-798.3-10(b)(11)), and the Hawaii TANF care deduction covers incapacitated adults only (HAR 17-676-54.1); and SSI stops counting food as in-kind support and maintenance from September 30, 2024, with the ISM chain and countable income computed monthly.
