Add Copy to Clipboard button on web interface for share links

On the web interface, when you right-click a folder > Share, a floating window opens with the link with a message on the bottom to copy the link to clipboard by pressing Ctrl+C.

It would be more convenient to have one of the buttons be "copy to clipboard", as currently the mouse-based process is hybrid by ending with a keyboard input.

The user can always right click on the link and copy to clipboard, but many techtard users won't know this feature, and this varies by browser, and it also involves more clicks than just having a Copy to Clipboard button being one of the buttons in the floating window with the link.
