add per-container handling options for hazardous, reefer, and return services

- Introduced new boolean fields (isHazardous, isReefer, isReturn) in UnitDraft and related interfaces to allow individual container handling options.
- Updated emptyUnit function to initialize these new fields.
- Modified GlCreateBookingForm to handle and display these options for each container.
- Adjusted calculations for hazardous, reefer, and return quantities based on the new handling options.
- Updated the schema for container units and booking container lines to include handling options.
- Added migration to support the new return flag in the database.
- Enhanced various components to reflect gross weight calculations, ensuring consistency across the application.
