Fix metrics correctness, redesign stats page

Browse Source 
- Replace stale snapshot read (GetCurrentMetrics) with live query
  (GetLiveMetrics) against sandboxes table — always returns correct
  zeros when no capsules are running
- Fix CPU reserved formula: running + starting only; paused VMs no
  longer contribute vCPUs (RAM reservation for paused unchanged)
- Merge top cards into 3 paired Now/Peak cards with colored accent
  borders (green/blue/amber matching chart colors)
- Move Live badge from Running Capsules card to page-level header
- Add colored category dots to card and chart headers
- Charts stacked vertically, flex-1 to fill remaining page height
- vCPUs chart color changed to blue (#5a9fd4), RAM stays amber
