🔍 ENHANCED ERROR LOGGING: Detailed React error messages and debugging

COMPREHENSIVE ERROR LOGGING SYSTEM:
✅ Created detailed error logging system with React error code mappings
✅ Enhanced SafePageView error boundary with detailed logging
✅ Added development error override system for better error messages
✅ Forced React development mode for non-minified errors

KEY IMPROVEMENTS:

🚨 Detailed React Error Logging:
- Maps minified React error codes to detailed explanations
- Provides specific debugging steps for hydration errors
- Shows common causes and solutions for each error type
- Includes component context and stack traces

🔍 Enhanced Error Messages:
- React #185: Detailed hydration error explanation with debugging steps
- React #418-421: Comprehensive error descriptions and solutions
- Automatic detection of hydration-related errors
- Context-aware error logging with component information

⚡ Development Mode Forcing:
- Forces React development builds for better error messages
- Overrides console.error to provide enhanced React error details
- Adds hydration error detection and logging
- Webpack configuration to use development React builds

This will give you comprehensive error information instead of cryptic minified React errors! 🔍✨
