Merged PR 1932: feat(remission): ensure package assignment before completing return receipts

feat(remission): ensure package assignment before completing return receipts

Add validation to check if a package is assigned to a return receipt before
allowing completion. When no package is assigned, automatically open the
package assignment dialog to let users scan/input a package number.

- Add hasAssignedPackage input to complete component and pass from parent
- Integrate RemissionStartService.assignPackage() in completion flow
- Add assignPackageOnly flag to conditionally hide step counter in dialog
- Update dialog data structure to support direct package assignment mode
- Enhance test coverage for new assignment scenarios

This ensures all completed return receipts have proper package tracking
and improves the user workflow by guiding them through required steps.
