Update HI TANF Standard of Assistance rate from 48% to 62% (effective March 1, 2025)

[hua7450]

Summary

Hawaii increased the TANF/TAONF monthly assistance allowance from 48% to 62% of the standard of need, effective March 1, 2025. This updates gov.states.hi.dhs.tanf.standard_of_assistance.rate (previously 2009-07-01: 0.48) so benefits from March 2025 onward are correct.

The standard of need itself ($1,590 for a family of 3) is unchanged — it remains frozen at 100% of the 2006 Hawaii FPL. Only the assistance-allowance rate (share of the standard of need actually paid) increased.

Closes #8654

Change

	Rate	SOA (family of 3)	After 20% mandatory-work reduction
Before (2009-07-01)	0.48	$763.20	$610.56 (CBPP's $610)
After (2025-03-01)	0.62	$985.80	$788.64

DHS worked example: "family of three with no income will see a change from $610 (with the 20% reduction) to $789, an increase of $179 per month." Statutory band per HRS §346-53: floor 48%, ceiling 62.5%.
