fix: strip trailing .0 in formatCompactCurrency for consistent cross-environment output

Fixes CI test failure where Intl.NumberFormat produced "$150.0K" instead of "$150K"
in certain Node.js/ICU versions. The regex strips trailing ".0" before compact suffixes
(K/M/B/T) while preserving meaningful decimals like "$1.5M".
