feat: Refactor closing services and add ClosingKeuanganService

- Updated ClosingRoutes to include ClosingKeuanganService.
- Removed GetClosingKeuangan method from ClosingService interface and its implementation.
- Introduced new ClosingKeuanganService with GetClosingKeuangan method to handle financial logic.
- Implemented detailed logging and error handling in the new service.
- Added GetTotalWeightProducedFromUniformityByProjectFlockID method in RecordingRepository to support weight calculations.
- Enhanced the logic for fetching and classifying product usage data by flags.
- Built comprehensive DTO responses for HPP and Profit Loss sections.
