Settings page API key improvements

We have made several improvements to the API key section on the Settings page.

What changed

Fixed API key information tooltips so they are no longer clipped inside the settings card.

Converted Demo and Live API key cards into collapsible panels.

Added clear API key status badges to show whether keys are set or still need to be added.

Added glowing status dots so users can quickly identify ready and missing key states.

These changes make the Settings page cleaner and make it easier to understand whether Demo or Live API keys still need attention.
