Suggested implementation steps (full E2E verification)

Goal: Verify a bank withdrawal can be linked to a supplier payment and the link is persisted/visible.

1. Prerequisites: Use testBankAccount; ensure test supplier contact exists.
2. Create & post supplier invoice: Use supplier-invoice API/helpers with a product. Store supplier invoice ID and amount.
3. Create payment: createPaymentViaAPI (payment-helpers) with contactId, amount, payMode: 'BANK', invoiceMappings: [{ invoiceId, amount }]. Store paymentId.
4. Create withdrawal: createWithdrawalTransaction (bank-account-helpers) with same amount.
5. Get transaction ID: getTransactionList(..., { transactionType: 'WITHDRAWAL' }) → find new transaction → transactionId.
6. Link: If backend has matchTransactionWithPayment (or similar), add helper and call it. Else perform linking via UI on reconciliation page (link/match/explain control).
7. Verify: API and/or UI – transaction shows linked payment (or supplier invoice).

Note: Repo has matchTransactionWithInvoice and matchTransactionWithReceipt in reconciliation-helpers. Check backend for transaction–payment (supplier) match endpoint; add helper if needed.
