merge: Remove use of Sass (#116)

This pull request removes the dependency on Sass for the OpenDC web UI, by converting
the existing Sass files into CSS. With the recent updates of CSS, we have no use-case for
Sass anymore and sticking to CSS reduces the build infrastructure necessary.

## Implementation Notes :hammer_and_pick:

* Drop dependency on Sass 
* Update web dependencies to latest version
