Implement Copy Login Command Feature

The feature aims to provide users with the ability to copy a "login command" from the ChRIS ui, facilitating easy access to the CLI login functionality.

• The feature aims to provide users with the ability to copy a "login command" from the ChRIS ui, facilitating easy access to the CLI login functionality. However, there are several considerations and questions that need to be addressed:
• Clipboard Access: Utilize a method to write to the clipboard that is compatible with HTTP protocols since navigator.clipboard does not work over HTTP.
• Placement and Styling: Determine the optimal placement for the "Copy Login Command" button within the UI. Define the styling guidelines for the button to ensure consistency with the overall design.
• Functionality: Define the behavior of the button when clicked. Should it immediately copy the login command to the clipboard, or should there be additional steps involved?
• Help Text/Documentation: Consider providing contextual help text or documentation about how to use the "Copy Login Command" feature. This could include instructions on accessing the CLI login functionality and utilizing the copied command.
• User Experience: Assess whether to keep the button unadvertised or to include it prominently within the interface. Consider user feedback and usability testing to optimize the user experience.

Steps to Reproduce:

• Install ChRIS by following the instructions provided in the ChRIS Project documentation.
• Login to the ChRIS ui at https://app.chrisproject.org/login.
• Click the dropdown menu in the masthead.
• Click "CLI login".
• Open a terminal and paste the copied login command.
• Run chrs list to verify functionality.
