+- REQUIRED: Always populate "bank_acc_name". RULES:
+1) If a field explicitly labeled as bank account (examples: "Account name", "Account holder", "Beneficiary", "Beneficiary name", "Account:", "Account Name:", "Bank acc name:") exists, set bank_acc_name to that exact text.
+2) Otherwise set bank_acc_name = sender_name (the value extracted from explicit sender/company fields).
+3) Always also extract sender_name separately from sender/company sections.
+4) Never leave bank_acc_name empty unless both bank and sender/company are absent — then set bank_acc_name = ""

 - Preserve original number formatting (including commas, decimals), Do not include currency symbol for amount field.
 - If multiple line items exist, include all of them in the items array
 - Use empty string "" for any field that is not present or cannot be clearly identified
