Update MainModule to support component priority field:
- Read component priority from column E of [产品订单] worksheet
- Pass component priority to ProcessSingleModel function
- Apply category exclusion logic based on priority flag:
- When "否"/"0"/"FALSE", exclude "部件" category
- Only extract sub-category materials when disabled
- Consistent with BIPUploadModule implementation
