Enhance banking transaction data structure and validation

- Increased the length of the NameOfPayer field from NVARCHAR(60) to NVARCHAR(140) in the banking transactions function, table, temporary table, and user-defined type to accommodate longer names.
- Expanded the SepaRemittanceInformation field from VARCHAR(150) to VARCHAR(200) in the banking transactions function for more detailed remittance information.
- Modified the stored procedure fds__setBankingtransaction_done to return additional transaction data (ValueDate and Amount) along with the success flag for improved notification messaging.
- Added validation in MFRClientConfig constructor to ensure the provided URL is not null or empty, enhancing error handling for configuration settings.
