Let me check if there's a ThemeProvider setup and the API proxy:

Good, the theme provider exists but I need to check if it's being used in the layout. Let me also read the proxy API route:

Now I have a complete picture. Let me make the following improvements:

1. Add ThemeProvider to layout.tsx for proper dark/light mode switching
2. Create a proper notification panel with real alerts
3. Improve the graphics with better colors and styling
4. Make real API connections work properly

Now let me update the globals.css to have a proper light theme:

Now create a notification panel component:

Now update the dashboard header to use the new notification panel:

Now update the dashboard index to pass the new props:

Now let me update the server control panel to make real API calls:

Now let me update the integration config to have better real API connection handling:

Now let me improve the overall UI with a better header design:

Now let me update the footer for a cleaner look:

Now let me update the tabs for a more modern look:

Now let me also add toast notifications for actions using sonner:

Now let me also add toast to the integration config:

I've made comprehensive improvements to the dashboard:
