refactor(web/ui): Drop dependency on Sass

This change updates the OpenDC web UI to not rely on Sass for
stylesheets. CSS in combination with PostCSS has become powerful enough
for our use-cases as indicated by the small differences between the CSS
and SCSS versions of our files.

By switching to CSS, we can make use of Turbopack to build the project,
which is a re-implementation of Webppack in Rust and is able to build
projects much faster.
