Updated GUI

Last week was tech debt week. There were a few things waiting for a big refactor and they are all done now. On of the most visible is a more consistent GUI style, with better contrast. There might still be some tweaks coming.

In the backend, which none of you see, we now have nice workflows to keep track of operational work like maintaining supplier mappings, discovery settings and lists, and other reviews. Internal service alerts have moved to Matrix, a European messaging system gaining traction in some North-West European countries.
