Backport https://github.com/go-gitea/gitea/pull/23481, https://github.com/go-gitea/gitea/pull/23504 and https://github.com/go-gitea/gitea/pull/23520 to 1.19, just so we have an easier time with future backports. Seems to work on a basic level. There was a merge conflict in `RepoActionView.vue`, otherwise it merged cleanly. --------- Co-authored-by: John Olheiser <john.olheiser@gmail.com> Co-authored-by: Lauris BH <lauris@nix.lv>
