fix: resolve all vizualni-admin build issues for CI/CD

- Fix GraphQL devtools import resolution with robust module structure
- Create environment-aware devtools that work in production and CI/CD
- Add comprehensive GraphQL client with error handling and retry logic
- Enhance webpack configuration for React 18 compatibility
- Fix Next.js configuration warnings (remove deprecated appDir, fontLoaders)
- Resolve React export conflicts for @dnd-kit, @emotion, @mui packages
- Add proper TypeScript path mapping for GraphQL modules
- Ensure builds work consistently across development, CI/CD, and production

This resolves all build failures and ensures reliable deployment pipeline.

+# GraphQL DevTools Module Resolution Fix
+
+## Problem
+The build was failing in CI/CD environments with the error:
+```
+Failed to compile.
+./graphql/client.tsx
+Module not found: Can't resolve '@/graphql/devtools'
+```
+
+## Root Cause
+1. **Missing GraphQL Module**: The `@/graphql/devtools` module was missing from the repository
+2. **Inconsistent Path Resolution**: Webpack aliases were not configured consistently across environments
+3. **TypeScript Path Mapping**: TypeScript configuration was missing explicit path mapping for the GraphQL module
+
+## Solution Implemented
+
+### 1. Created Complete GraphQL Module Structure
+**File**: `/amplifier/scenarios/dataset_discovery/vizualni-admin/graphql/`
+
+- **`devtools.ts`**: Robust GraphQL devtools implementation with:
+  - Environment-aware enabling (development only)
+  - Request/response logging
+  - Error handling and validation
+  - Production-safe operation
+
+- **`client.tsx`**: Complete GraphQL client with:
+  - Proper TypeScript typing
+  - Error handling and retry logic
+  - Request timeout management
+  - Devtools integration
+  - Environment variable support
+
+- **`index.ts`**: Clean module exports for easy imports
+
+### 2. Fixed Webpack Configuration
+**File**: `next.config.js`
+- Added explicit webpack alias for `@/graphql` mapping
+- Ensures consistent module resolution across environments
+
+```javascript
+webpack: (config) => {
+  config.resolve.alias = {
+    ...config.resolve.alias,
+    '@/graphql': require('path').resolve(__dirname, 'graphql'),
+  };
+  return config;
+},
+```
+
+### 3. Updated TypeScript Configuration
+**File**: `tsconfig.json`
+- Added explicit path mapping for GraphQL module
+- Ensures TypeScript understands the `@/graphql/*` imports
+
+```json
+"paths": {
+  "@/graphql/*": ["./graphql/*"]
+}
+```
+
+## Features of the Solution
+
+### GraphQL DevTools (`devtools.ts`)
+- **Environment-Aware**: Automatically enables in development, disables in production
+- **Comprehensive Logging**: Request, response, and error logging
+- **Type-Safe**: Full TypeScript support
+- **Zero Dependencies**: No external devtools dependencies required
+- **Production Safe**: Zero overhead in production builds
+
+### GraphQL Client (`client.tsx`)
+- **Robust Error Handling**: Comprehensive retry logic and timeout management
+- **DevTools Integration**: Seamless integration with devtools when available
+- **TypeScript Support**: Full type safety for requests and responses
+- **Environment Configurable**: Supports environment variables for configuration
+- **Singleton Pattern**: Optional default client instance for easy usage
+
+## Testing Results
+✅ **Production Build**: Successful compilation and build
+✅ **Development Build**: Development server starts without errors
+✅ **TypeScript Compilation**: No type errors
+✅ **Module Resolution**: All imports resolve correctly
+✅ **CI/CD Compatibility**: Works in continuous integration environments
+
+## Usage Examples
+
+### Basic GraphQL Client Usage
+```typescript
+import { createGraphQLClient } from '@/graphql';
+
+const client = createGraphQLClient({
+  endpoint: 'https://your-graphql-endpoint.com/graphql',
+  enableDevTools: true, // Only works in development
+});
+
+const data = await client.query(`
+  query GetUser($id: ID!) {
+    user(id: $id) {
+      id
+      name
+      email
+    }
+  }
+`, { id: '123' });
+```
+
+### Using DevTools Directly
+```typescript
+import { devtools } from '@/graphql';
+
+// DevTools automatically log requests/responses in development
+// No manual setup required
+```
+
+## Environment Variables
+```bash
+# Optional: Configure default GraphQL client
+NEXT_PUBLIC_GRAPHQL_ENDPOINT=https://your-graphql-endpoint.com/graphql
+NEXT_PUBLIC_NODE_ENV=development
+```
+
+## Files Modified/Created
+
+### New Files
+- `/amplifier/scenarios/dataset_discovery/vizualni-admin/graphql/devtools.ts`
+- `/amplifier/scenarios/dataset_discovery/vizualni-admin/graphql/client.tsx`
+- `/amplifier/scenarios/dataset_discovery/vizualni-admin/graphql/index.ts`
+
+### Modified Files
+- `/amplifier/scenarios/dataset_discovery/vizualni-admin/next.config.js`
+- `/amplifier/scenarios/dataset_discovery/vizualni-admin/tsconfig.json`
+
+## Benefits
+1. **CI/CD Compatibility**: Works reliably in all build environments
+2. **Development Experience**: Enhanced debugging with devtools in development
+3. **Zero Production Impact**: DevTools completely disabled in production
+4. **Type Safety**: Full TypeScript support throughout
+5. **Error Resilience**: Robust error handling and retry logic
+6. **Environment Flexibility**: Works with different GraphQL endpoints per environment
+
+## Verification Commands
+```bash
+# Test build
+npm run build
+
+# Test development
+npm run dev
+
+# Test TypeScript compilation
+npx tsc --noEmit
+```
+
+This fix permanently resolves the `@/graphql/devtools` module resolution issue and provides a robust GraphQL client that works consistently across all environments.
