First step in the AdminTrafficUsage decomp. Two new files under
src/components/admin/trafficUsage/:
- trafficUsageHelpers.ts (166 lines): the TanStack Table module
augmentation (sticky/align/bold meta), formatters (formatBytes,
formatCurrency, formatShortDate, formatGbPerDay,
toBackendSortField, getFlagEmoji wrapper), risk-assessment helpers
(bytesToGbPerDay, getRatio, getRowBgColor, getNodeTextColor,
getRiskLevel, getCompositeRisk), and the RISK_STYLES constant.
- RiskBadge.tsx (36 lines): the small per-row risk indicator
(dot + GB/d value + mini progress bar). Pure presentational.
Parent imports everything from the new modules; the inline
'TanStack Table module augmentation' lives in the helpers file
so the declaration merge still picks up across the codebase
once the helpers are imported.
AdminTrafficUsage.tsx: 1904 → 1734 lines (-170).
