feat(MemberOrder, MemberOrderHistory, MemberOrderService, OrdersPanel): add paidConfirmed field and update related logic

- Introduced a new boolean field `paidConfirmed` in MemberOrder and MemberOrderHistory models to track payment confirmation status.
- Updated serialization functions in MemberOrderService to include `paidConfirmed` in order and history entries.
- Enhanced OrdersPanel component to allow users to set and display the `paidConfirmed` status for orders.
- Added localization support for the new `paidConfirmed` label in German.
- Adjusted related logic to ensure proper handling of the `paidConfirmed` state throughout the application.
