US-3.13not implemented Handle a foreign-currency receipt with returned items
As a user who bought and returned items in GBP on the same receipt (net amount in GBP differs from gross) I want match the net GBP amount (converted to EUR) to my bank CSV so that only the net charge appears in my journal.
Acceptance Criteria
- The receipt has both `net_bought_items` and `net_returned_items` with GBP account transactions.
- The matcher computes the net GBP amount, converts to EUR, and searches the CSV.
- Currently raises `NotImplementedError("Do not yet know how to handle the scenario of multiple transacted items per receipt for foreign currency withdrawl receipts.")`.
No DAG diagram: Not yet implemented — once built, the data path will extend US-3.3 (foreign-currency matching) with net-amount computation for returns.
