Refactor transaction data handling in LamassuTransactionProcessor: Improved consistency in processing None and empty values during data ingestion. Defaulted numeric fields to 0 and percentage fields to 0.0 for better error handling. Ensured clean extraction of transaction details, enhancing reliability in transaction processing.
