💬 Implement complete chat-based agent system with 5 Whys Analysis

🏗️ **Database Extensions:**
- Add agent_type field to Agent model (form/chat distinction)
- Create ChatSession model for conversation management
- Create ChatMessage model for message storage with metadata
- Add database indexes for performance optimization

🎨 **Frontend Implementation:**
- Create agent_chat.html template with modern chat interface
- Implement real-time messaging UI with message bubbles
- Add typing indicators and loading states
- Responsive design for mobile and desktop
- Empty states and error handling

🔧 **Backend Logic:**
- Extend agent_detail_view to route chat vs form agents
- Implement chat_agent_view for chat interface rendering
- Add start_chat_session API endpoint with session management
- Add send_chat_message API endpoint with webhook integration
- Add get_chat_history and end_chat_session endpoints
- Session-based fee charging system

🤖 **5 Whys Agent:**
- Create "Analysis & Problem Solving" category
- Implement 5 Whys Analysis chat-based agent (15 AED)
- Interactive problem-solving methodology guidance
- N8N webhook integration for AI responses

 **Interactive Features:**
- JavaScript ChatInterface class for real-time communication
- Auto-session creation and management
- Message validation and error handling
- Automatic scrolling and UI state management
- CSRF protection and security measures

🔗 **API Integration:**
- Chat-specific API endpoints with RESTful design
- Webhook payload formatting for N8N integration
- Session ID tracking and conversation continuity
- Metadata storage for webhook responses

🛡️ **Security & UX:**
- Login required for chat agents
- Wallet balance validation before session creation
- Session isolation per user and agent
- Comprehensive error handling and user feedback

**New URLs:**
- /agents/api/chat/start/ - Start new chat session
- /agents/api/chat/send/ - Send chat message
- /agents/api/chat/history/<session_id>/ - Get chat history
- /agents/api/chat/end/ - End chat session
- /agents/five-whys-analysis/ - 5 Whys chat interface

**Backward Compatibility:**
- Existing form-based agents (Social Ads, Job Posting, PDF) unchanged
- Admin interface updated to show agent types
- Marketplace displays both agent types seamlessly

🚀 Ready for interactive 5 Whys problem-solving conversations\!
