feat(remission): refactor return receipt details and extract shared actions

Refactor remission return receipt details to use return-based data flow
instead of individual receipt fetching. Extract reusable action components
for better code organization and consistency.

- Remove deprecated fetchRemissionReturnReceipt method and schema
- Add helper functions for extracting data from return objects
- Replace receipt-specific components with return-based equivalents
- Create shared return-receipt-actions library with reusable components
- Update components to use modern Angular patterns (signals, computed)
- Improve data flow consistency across remission features
- Add comprehensive test coverage for new components
- Update eager loading support in fetch return functionality

The new architecture provides better data consistency and reduces
code duplication by centralizing receipt actions and data extraction
logic into reusable components.
