feat(dc): Add multi-metric transformation feature (direction 1+2)
Summary: - Implement intelligent multi-metric grouping detection algorithm - Add direction 1: timepoint-as-row, metric-as-column (analysis format) - Add direction 2: timepoint-as-column, metric-as-row (display format) - Fix column name pattern detection (FMA___ issue) - Maintain original Record ID order in output - Add full-select/clear buttons in UI - Integrate into TransformDialog with Radio selection - Update 3 documentation files Technical Details: - Python: detect_metric_groups(), apply_multi_metric_to_long(), apply_multi_metric_to_matrix() - Backend: 3 new methods in QuickActionService - Frontend: MultiMetricPanel.tsx (531 lines) - Total: ~1460 lines of new code Status: Fully tested and verified, ready for production
