Optimize BIPUploadModule and MainModule for better performance:
- Replace cell-by-cell writes with batch array operations
- Collect all output data in memory using Collection objects
- Use WriteBatchData to write all data in single operation
- Add CreateBIPRowArray and CreateOutputRowArray helper functions
- Remove deprecated WriteBIPRow and WriteOutputRow functions
Performance improvement:
- Before: N cell write operations per row (thousands of Excel calls)
- After: 1 batch write operation for all data
- Expected speedup: 10-100x depending on data volume
