Refactor strategy pattern to implement separation of concerns

- Update IModuleProcessor interface to accept targetBOMs collection instead of targetItemName string
- Remove filtering logic from strategy implementations (AppendOnly, CloneNew)
- Add LoadData method to mSpecAdditionManager for UI initialization
- Rename ExecuteAddition to ExecutePipeline with refined parameters
- Enhance test suite to simulate fine-grained UI selection behavior
- Enable precise row-level control by delegating filtering to UI layer

This refactoring achieves better separation of concerns where:
- Strategy layer focuses purely on execution logic
- UI layer handles selection and filtering
- Manager layer coordinates the pipeline flow
