- Update approval status values to use correct API parameter ('0,1' for pending, '2' for completed)
- Rename status parameter to approve_status to match API specification
- Fix timestamp field reference from create_time_cn to create_time for proper data binding
- Ensures approval list correctly filters and displays applications based on status
