SFTP Fragment results in invalid XML due to incorrect order of child elements

Current Behavior:

When an SFTP fragment is created, adding PreferredAuthentications or RequiredAuthentications results in these elements being inserted before the Account element in the generated XML.
This causes a schema validation error:

• 'PreferredAuthentications', line=1, column=461, cvc-complex-type.2.4.a: Invalid content was found starting with element 'PreferredAuthentications'. One of ' {Account}
  ' is expected.

Because of this error, the configuration becomes invalid and cannot be deployed unless the XML is manually corrected.

Desired Behavior:
The YADE GUI should generate SFTP fragment XML elements in the correct schema-defined order, ensuring that PreferredAuthentications and RequiredAuthentications are added after the Account element.

Workaround:
The issue can be addressed by manually editing the XML and placing the Account element before the PreferredAuthentications or RequiredAuthentications element.
