refactor: split DashboardScreen into ServiceBalanceCards

- New: ServiceBalanceCards.kt (511 lines) — all service balance Composables +
  CompactUsageRow/CompactUsageRowEmpty + utility functions
  (formatAmount/formatResetInSec/normalizeWindowLabel/statusBadgeStyle/
  secondaryLine/footerText)
- DashboardScreen.kt: 1121 → 637 lines (-43%)
  Retained: DashboardScreen main + DraggableDashboardCards + DashboardCard +
  DashboardFooter
- All functions changed from private to internal for cross-file visibility
- No behavior change
