refactor: optimize data cleanup functions in director console

- Add redrawCurrentRound() method to clear current round winners
- Add /api/admin/lottery/redraw API endpoint
- Rename "重置" to "重置本轮" (reset current round state only)
- Add "重抽本轮" button (clear winners and allow re-draw)
- Rename "紧急操作" to "数据管理" with clearer button labels
- Change "高级清理" to collapsible "开发者选项"
- Update confirmation modal text for clarity
