Implement secure N8N webhook integration and resolve CORS issues
### 🔧 Technical Solution - **API Key Authentication**: Migrated from Authelia session auth to X-N8N-API-KEY header authentication - **CORS Resolution**: Eliminated preflight failures by removing authentication redirects from webhook endpoints - **Error Handling**: Added graceful fallback for empty N8N responses with intelligent question generation - **Type Safety**: Updated TypeScript interfaces for enhanced response format support ### 🛡️ Security Enhancements - **Maintained Security**: N8N UI still protected by Authelia while webhooks use API key authentication - **Audit Trail**: All webhook requests logged with API key identification for security monitoring - **Rate Limiting**: Applied through Traefik middleware to prevent API abuse - **Easy Key Rotation**: API keys can be changed instantly without affecting user sessions ### 📱 Application Updates - **N8nSyncService**: Complete migration from Authelia to API key authentication - **CV Upload Component**: Simplified flow without authentication popups for N8N integration - **Fallback System**: Intelligent question generation based on CV content when N8N unavailable - **User Experience**: Seamless PDF upload to analysis workflow without CORS barriers ### 🐳 Docker Configuration - **Multi-stage Build**: Optimized Dockerfile with Node.js 20 and nginx:alpine - **Docker Compose**: Complete service orchestration with port 3007 mapping - **Nginx Configuration**: Custom MIME types for PDF.js worker files and SPA routing - **SSL Integration**: Traefik labels for automatic HTTPS with proper CORS headers ### 🧪 Testing Results - ✅ **PDF Processing**: Successfully extracts text from uploaded CVs (2871+ characters) - ✅ **CORS Success**: OPTIONS and POST requests work without authentication redirects - ✅ **Webhook Integration**: Connects to N8N with X-N8N-API-KEY header - ✅ **Fallback Questions**: Generates contextual questions when N8N workflow unavailable - ✅ **Type Safety**: No TypeScript compilation errors with updated interfaces ### 💡 Intelligent Fallback Features - **Technical Questions**: Generated based on actual CV skills (e.g., JavaScript experience) - **Behavioral Questions**: Standard problem-solving and teamwork assessments - **Experience-Specific**: Company and role-specific questions from work history - **Career Development**: Growth and motivation questions tailored to experience level ### 🔗 Integration Points - **Environment Config**: Added N8N API key and base URL configuration - **Service Communication**: Direct HTTP with API key headers (no session dependency) - **Response Handling**: Support for both N8N workflow responses and local fallback - **Error Recovery**: Graceful degradation when external services unavailable 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
