icy 5bd6333b7b Optimize /api/competition endpoint performance with concurrent data fetching and caching ...

## Performance Improvements:
- **Concurrent Processing**: Replace serial GetAccountInfo() calls with parallel goroutines
- **Timeout Control**: Add 3-second timeout per trader to prevent blocking
- **30-second Cache**: Implement competition data cache to reduce API calls
- **Error Handling**: Graceful degradation when API calls fail or timeout

## API Changes:
- Reduce top traders from 10 to 5 for better chart performance
- Update /api/equity-history-batch to use top 5 traders by default
- Add detailed logging for cache hits and performance monitoring

## Expected Performance Gains:
- First request: ~85% faster (from 25s to 3s for 50 traders)
- Cached requests: ~99.96% faster (from 25s to 10ms)
- Better user experience with consistent response times
