2650960 - Migration Cockpit: File extension missing after downloading template file

The download process in web browsers such as Google Chrome or Firefox automatically removes the '.XML' extension from the template file. Saving the file with a non-XML extension (such as '.XLSX') creates a structurally invalid file. 

Although the data appears correctly displayed in Excel, it is shifted to incorrect fields in the migration cockpit's staging table. This mismatch results in unusual error messages from the API during import and causes the data to be stored in the wrong database fields.

Example: In the BANK Data template file, SWIFT codes are uploaded to the STREET field in the staging area.
