CB/ui: move style overrides to this repo (!53)

Moves the contents of codeberg.css from the Codeberg-Infrastrcuture/build-deploy-forgejo repository to this one, converting them to a less file.

Also adds overrides to swap the Codeberg logo to the blue version when the theme uses a light background for the header and footer.
