Issue Description
The Notifications panel (slide-out) does not respect the "Black" Dynamix color theme. While the rest of the WebGUI correctly applies the dark theme, the notification panel background remains white/light. This results in a visual inconsistency and potential legibility issues if the text color is optimized for a dark background.

Steps to Reproduce
Navigate to Settings > Display Settings.

Set Dynamix color theme to "Black" (or "Dark").

Click the Notifications (bell icon) in the top right header to open the slide-out panel.

Observe that the panel background is white/light instead of black.

Expected Behavior
The Notification panel background color should match the selected "Black" theme (dark background) to ensure consistency with the rest of the UI and proper text readability.

Actual Behavior
The Notification panel background renders in white/light mode, ignoring the selected system theme.

Additional Context
This appears to be a regression in the 7.2.x series regarding the new responsive UI or the Unraid API-driven notifications. It has been observed by other users on the stable release where the slide-out uses light mode attributes despite the global theme settings.
