Feat: Add segmented progress bar for data extractor with dynamic phase calculation

- Add ExtractionProgress type with phase, batch, and subProgress fields
- Implement dynamic progress calculation: 1 (login) + N (batches) + 2 (merge/import)
- Create SegmentedProgressBar component with 4 colored phases (purple/blue/amber/green)
- Show batch-level progress during download phase (e.g., 批次 1/10)
- Display sub-progress during login phase (连接数据库/解析订单号/登录 ERP)
- Update IPC handler and extractor services to report detailed progress
- Add phase status indicators (completed/active/pending) with color-coded dots
