Answer 1

Please change the Save.php as below and you will get the order id

<?php
namespace Companyname\Modulename\Controller\Adminhtml\Order\Invoice;
ini_set('display_errors',1);
error_reporting(E_ALL);

use Magento\Sales\Api\Data\OrderInterface;
use Magento\Sales\Model\ResourceModel\Order\Invoice\CollectionFactory;

class Save 
{

    /**
     * @var Registry
     */
    protected $registry;

    /**
     * @param Registry $registry
     */
    public function __construct(
        \Magento\Framework\Registry $registry
    ) {
        $this->registry = $registry;
    }

    public function afterExecute(\Magento\Sales\Controller\Adminhtml\Order\Invoice\Save $subject, $result)
    {
        $invoice = $this->registry->register('current_invoice');
        $orderId = $invoice->getOrderId();
        $invoiceId = $invoice->getId();

        return $result;
    }
}

Answer 2

You can get the Order Id in this way.

class Save 
{
    public function afterExecute(\Magento\Sales\Controller\Adminhtml\Order\Invoice\Save $subject,$result)
    {
        $orderId = $subject->getRequest()->getParam('order_id');
        echo $orderId;
    }
}

Answer 3

  You can Try this
  Venddor/Module/etc/event.xml 

<event name="sales_order_save_after">
  <observer name="reward_ggn" instance="Vendor\Module\Observer\ClassName"/>
</event>

<?php

namespace Vendor\Module\Observer;

use Magento\Framework\Event\ObserverInterface;


class ClassName implements ObserverInterface 
{

 public function execute(\Magento\Framework\Event\Observer $observer) 
 {      
    $order = $observer->getEvent()->getOrder();

            if($order->getState() == 'complete') {
               
            $order->getOrderId();
            }       
 }
 }
