Обсуждение: [pgAdmin][RM4930] [Accessibility] Main window tan navigation

Hi Hackers,

Please find a patch for following accessibility issues on the main window.

1. Dashboard -> Server Activity grid: terminate the session, cancel active button not navigable using tab key
2. SQL -> If the focus inside code mirror control tab navigation not working

Along with this, there is a minor shadow color fix for the refresh button on the Server activity grid's refresh button. Note: Currently search text field has a primary-color shadow and the refresh button has a secondary-color shadow.
