Make tabs smaller (#12003)

* Make tabs smaller

Fomantic's tabs are excessively wide and with another tab added on the
repo tabbar (https://github.com/go-gitea/gitea/pull/8346) it would break
the layout on the english language.

Globally reduce tab bar padding to around half of the previous values.

* disable no-duplicate-selectors linter rule

* more tab bar tweaks

* more tweaks

* merge rules and nesting

* remove arc-green weird hover color

* few more arc-green tweaks

* restore to 12px

* tweaks

* use half width height padding

* final tweak

* 10px

* remove min-height

* 11px

* remve new-menu background on light theme too

* background fixes for new-menu
