Admin dashboard: fix stats waterfall, redesign layout, add animations

- Fetch dashboard stats server-side in admin/page.tsx to eliminate
  client-side useEffect waterfall and the '—' placeholder flash
- Pass pre-fetched stats as props to DashboardClient
- Lazy-load UpgradePlanModal via next/dynamic (only loads when needed)
- Redesign stats cards with compact layout, smaller icons, Fraunces serif values
- Improve Quick Actions + Usage row: side-by-side on desktop, stacked mobile
- Clean up Recent Orders as a proper list with icon/name/time/amount/badge
- Add staggered fade-up entrance animations (0/60/120/180/240ms delays)
- Consolidate loading.tsx skeleton to match actual dashboard structure
- Mobile-responsive: 2-col stats on mobile, stacked usage, collapsible header
