- Hotfix to restore the course overview.
- Various improvements to efficiency and safety.

There is a new version of Moodle that breaks compatibility with this plugin. This is a hotfix to ensure basic functionality is restored.

Note: Moodle now supports dark mode natively, so this plugin now switches to dark mode based on the Moodle setting.

- Significantly improved loading speed. This also makes the white flash shorter when reloading a page with dark mode enabled. It is unfortunately not feasible to completely remove it.

- Fixed page layout on subpages. They will now shrink to the middle of the screen if the content is narrow.

- Significantly improved general styling. Links are now styled correctly, eliminating the funky boxes behind them and the color flashes when hovering over them. More buttons now follow the default styling, which is especially important in dark mode, because they would be in light mode. There are many more minor styling improvements.
