Add event handler for checkbox changes to manage refresh button state

- Implemented a new event listener for checkboxes with class 'g-checkbox'.
- The listener updates the state of the '.multi-refresh' button based on the checked status of the checkbox.
- Ensured that the refresh button is enabled or disabled appropriately when checkboxes are checked or unchecked.
