Pull Request Overview

This PR disables the sign-in functionality when Dynamo is running in "no network mode" to provide a better user experience by preventing failed authentication attempts when network connectivity is unavailable. The changes introduce logic to conditionally disable the login menu and provide appropriate user feedback.

• Disables the login menu when NoNetworkMode is enabled
• Updates tooltip text to inform users how to enable sign-in functionality
• Ensures tooltip is visible even when the button is disabled
