feat: complete stream detail page redesign with moon theme

- Redesigned stream/[id]/page.tsx with moon theme nebula backgrounds
- Created StreamHeader component with org avatar, status badge, sender/receiver
- Created FlowRateGauge with animated SVG semi-circle gauge (green to cyan)
- Created BalanceProjectionChart using Recharts with green-yellow-red color shift
- Created ProgressBar with animated progress and days/weeks remaining display
- Created TransactionHistory with pagination (20 per page), type icons, status badges
- Created ActionButtons with 5 action buttons, ripple animation, and modals
- Created StreamSkeleton for loading states with shimmer effects
- Created StreamError with retry button
- Updated ViewStreamClient with WebSocket real-time updates (socket.io)
- All components use Stellar Glass design system with glass-card aesthetic
- Mobile-first single column layout with responsive grid
- Loading skeleton and error state with retry functionality
- Accessibility: aria-labels, keyboard navigation, semantic structure
