fix(frontend): marketplace page load and caching (#10934)

## Changes 🏗️

### **Server-Side:**
- ✅ **ISR Cache**: Page cached for 60 seconds, served instantly
- ✅ **Prefetch**: All API calls made on server, not client
- ✅ **Static Generation**: HTML pre-rendered with data
- ✅ **Streaming**: Loading states show immediately

### **Client-Side:**
- ✅ **No API Calls**: Data hydrated from server cache
- ✅ **Fast Hydration**: React Query uses prefetched data
- ✅ **Smart Caching**: 60s stale time prevents unnecessary requests
- ✅ **Progressive Loading**: Suspense boundaries for better UX

### **🔄 Caching Strategy:**

1. **Server**: ISR cache (60s) → API calls → Static HTML
2. **CDN**: Cached HTML served instantly
3. **Client**: Hydrated data from server → No additional API calls
4. **Background**: ISR regenerates stale pages automatically

### **🎯 Result:**
- **First Visit**: Instant HTML + hydrated data (no client API calls)
- **Subsequent Visits**: Instant cached page
- **Background Updates**: Automatic revalidation every 60s
- **Optimal Performance**: Server-side rendering + client-side caching
