Merged PR 1889: feat(remission-data-access, remission-list, remission-start-card): add remission item selection and quantity update logic

- Introduce `addReturnItem` and `addReturnSuggestionItem` methods to `RemissionReturnReceiptService` with full schema validation and error handling
- Add models and schemas for receipt-return tuples and add-return-item/suggestion operations
- Refactor `RemissionStore` (formerly `RemissionSelectionStore`) to support selection, quantity updates, and clearing of remission items; update all usages to new store name and API
- Update `RemissionListItemComponent` to support item selection via checkbox and quantity dialog, following workspace UX and state management guidelines
- Enhance `RemissionListComponent` to handle selected items, batch remission, and error/success feedback using new store and service APIs
- Fix and extend tests for new store and service logic, ensuring coverage for selection, quantity, and remission flows
- Update remission start dialog and assign package number components for improved validation and loading state handling
