Checkmk Werk 15927: Fix copy of random secret to clipboard

ID: 15927 Title: Fix copy of random secret to clipboard Component: Setup Level: 1 Class: Bug fix Version: 2.3.0b1 In some environments, the button "Create random secret and copy secret to clipboard" of the option "Automation secret for machine accounts" on the users page did not copy the secret to the clipboard. We now use a fallback mechanism if the standard fails. If even the fallback fails you will see a dialog were you can copy the secret manually.
