Fix HTTP error response body logging in AS2SenderModule

Problem

When a partner returns a non-2xx HTTP response code, the error log message displays the raw Java byte array reference instead of the actual response body content.

Example of current broken output:

Error sending message. URL: https://partner.com:443/as2/incoming ::: Response Code: 500 Internal error. ::: Response Message: [B@24733dd5

This is caused by calling .toString() on the byte[] returned by resp.getBody(), which in Java outputs the type prefix [B and the object hash code rather than the string content.

Fix

Replace .toString() with new String(resp.getBody(), StandardCharsets.UTF_8) to correctly decode the response body bytes into a readable string.

Changes

AS2SenderModule.java — sendMessage() method:

// Before
msg.setLogMsg("Error sending message. URL: " + url + " ::: Response Code: " + rc + " " + resp.getStatusPhrase() + " ::: Response Message: " + resp.getBody().toString());

// After
msg.setLogMsg("Error sending message. URL: " + url + " ::: Response Code: " + rc + " " + resp.getStatusPhrase() + " ::: Response Message: " + new String(resp.getBody(), java.nio.charset.StandardCharsets.UTF_8));

Impact

No behavioral change — error handling and resend logic are unaffected. This only improves the content of the log message so that partner error responses are human-readable, which significantly aids in debugging failed transmissions.
