Refactored the handling of `senderDoc.ByteData` by replacing
the ternary operator with an explicit `if` statement for better
readability. Added a `Content-Disposition` header to ensure
the file is displayed inline with a proper filename. Updated
the MIME type of the file response from `application/octet-stream`
to `application/pdf` to reflect the expected content type.
