Refactor data source to use dedicated parameter configuration worksheet

- Add mParamWorksheet variable for parameter configuration worksheet
- Load material names from dedicated [参数配置] worksheet instead of extracting from BOM data
- Implement validation for parameter configuration worksheet existence
- Add header row logic (row 2) with data starting from row 3
- Improve code comments for better clarity
- Remove debug output for cleaner production code
- Implement proper error handling for parameter worksheet access

This architectural improvement separates configuration data from operational data, following the single responsibility principle. The [参数配置] worksheet serves as a centralized configuration source for target material names, making the system more maintainable and allowing business users to manage target materials without touching the main BOM data.
