fix: timeframe handling and progress tracking improvements

- Fix timeframe parameter handling in enhanced-screenshot API route
- Support both 'timeframe' (singular) and 'timeframes' (array) parameters
- Add proper sessionId propagation for real-time progress tracking
- Enhance MACD analysis prompt with detailed crossover definitions
- Add progress tracker service with Server-Sent Events support
- Fix Next.js build errors in chart components (module variable conflicts)
- Change dev environment port from 9000:3000 to 9001:3000
- Improve AI analysis layout detection logic
- Add comprehensive progress tracking through all service layers
