fix: improve risk calculation display with actual GB/d values

- RiskBadge now shows real daily GB/d value + mini progress bar
- Node cells show daily rate subtitle when threshold is active
- Total column shows daily rate subtitle when threshold is active
- getCompositeRisk returns both ratio and dominant GB/d value
- formatGbPerDay helper for clean number formatting
