feat(BE): integrate FIFO service for stock adjustments and transfers

- Added FIFO service integration in the adjustments module to manage stockable and usable items for adjustments.
- Created a new repository for adjustment stocks to handle database operations.
- Enhanced the adjustment service to track stock adjustments using FIFO logic for both increase and decrease operations.
- Updated product warehouse DTOs and repositories to include project flock information.
- Implemented FIFO logic in the transfer module to manage stock transfers between warehouses.
- Added integration tests for FIFO operations in stock transfers, ensuring correct stock consumption and replenishment.
