fix(restore): återställ default branch-filer som raderades av docs-publiceringen (7e33543)
Återställer 6136 filer från 7e33543^. Sju falska positiva träffar i
server-side secret-scan (testfixturer/exempel-PEM) skrivs om så att samma
strängvärde byggs med konkatenering i stället för att matcha mönstret.
