fix: remove requestChecksumCalculation for S3 client on production

This partially reverts commit 2de6f26.

Fixes the following error on file uploads:

[Nest] 5  - 05/06/2025, 12:59:58 AM   ERROR [FileService] Error uploading file:
[Nest] 5  - 05/06/2025, 12:59:58 AM   ERROR [FileService] InvalidArgument: Unsupported header 'x-amz-checksum-crc32' received for this API call.

It seems like the Backblaze B2 API is not compatible with this header.
