fix: implement proper multi-timeframe batch analysis

- Create /api/batch-analysis endpoint that collects ALL screenshots first
- Then sends all screenshots to AI for comprehensive analysis
- Fixes issue where individual timeframes were analyzed immediately
- Multi-timeframe analysis now provides cross-timeframe consensus
- Update AIAnalysisPanel to use batch analysis for multiple timeframes
- Maintains backward compatibility with single timeframe analysis
