🔧 Fix Real-Time Stock Analysis & AI Visualizations Functionality

## ✅ Critical Interface Fixes:
- **Fixed Stock Analysis Tab** - Real-time stock analysis now working properly
- **Fixed AI Visualizations Tab** - DALL-E image generation interface now functional
- **Fixed Code Executor Tab** - Python code execution now properly connected

## 🐛 Root Cause Resolution:
- **Interface Component Connection** - Gradio components weren't properly connected to event handlers
- **Inline Interface Definition** - Moved interface components inline within tab contexts
- **Event Handler Binding** - Fixed click events for all interactive components

## 📈 Stock Analysis Features Now Working:
- Real-time stock data fetching with yfinance
- Interactive candlestick charts with moving averages
- Comprehensive financial analysis (Sharpe ratio, Beta, volatility)
- Multiple time period selection (1mo, 3mo, 6mo, 1y, 2y, 5y)

## 💻 Code Executor Features Now Working:
- Live Python code execution in secure environment
- Financial analysis examples pre-loaded
- Clear output display and code clearing functionality

## 🎨 AI Visualizations Features Now Working:
- DALL-E 3 image generation for financial visualizations
- Example prompts for financial charts and dashboards
- Proper error handling and user feedback

## 🔧 Technical Improvements:
- Proper Gradio component lifecycle management
- Fixed interface component return value handling
- Enhanced error handling throughout all tabs
