Remove CSS code that was made unused by some changes in Gitea. I was working on a layout change here but was bothered a bit by these. I dug a bit into the git history to find out how they were made unused but it's relatively uneasy.
- remove rule that was setting `width: 100%;`: the exactly same selector setting this exact value is duplicated below
- remove rules with `followers` in selectors: we don't use this class in templates (would be nice if someone double-checks)
- my editor forced EoF fix
