Add end-to-end test for Direct Reply-To message flow

[Copilot]

Addresses reviewer feedback that the Direct Reply-To test only verified queue address format without testing actual message send/receive functionality.

Changes

• Added test_direct_reply_to_send_and_receive test that exercises the full message flow:
  • Creates consumer with DirectReplyToConsumerOptions
  • Publishes messages to the dynamic reply-to address
  • Consumes and validates message content
  • Verifies all messages delivered successfully

def test_direct_reply_to_send_and_receive(environment: Environment, connection: Connection) -> None:
    consumer = connection.consumer("", consumer_options=DirectReplyToConsumerOptions())
    addr = consumer.get_queue_address()
    
    publisher = environment.connection().publisher(addr)
    publisher.publish(Message(body=Converter.string_to_bytes("test")))
    
    message = consumer.consume()
    assert Converter.bytes_to_string(message.body) == "test"

• Added proper cleanup for existing test_consumer_create_reply_name test
