refactor(pop): update popProductionController and routes

- Changed the `copyChecklistToSplit` function to be exported for better accessibility.
- Temporarily commented out the `getProcessList` and `getProcessResult` routes in `popProductionRoutes` due to missing implementations, with a note for future restoration.
- Updated the loop in `salesOrderBulkService` to use `Array.from()` for better clarity in iterating over entries.

These changes aim to improve code organization and maintainability while addressing current implementation gaps.
