MODEXPW-508 - Add UTF-8 BOM to files written to S3/Minio

Purpose

The purpose of this change is to address issues with Excel not properly displaying Arabic characters in CSV files exported from our system. By adding a UTF-8 Byte Order Mark (BOM) to the beginning of these files, we ensure that applications like Excel correctly recognize the file encoding as UTF-8, thus displaying Arabic characters properly.

Approach

To implement this change, we've modified the write method in our S3/Minio file writing utility. The approach involves:

• Defining the UTF-8 BOM as a byte array at the beginning of the method.
• Using a ByteArrayOutputStream to combine the BOM with the original file content.
• Writing the combined byte array (BOM + original content) to S3 or Minio.
