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.

/**
* Stamps public/sw.js from public/sw.template.js with the runtime brand name.
*
* The service worker is served as a static file (Next.js does not bundle
* public/), so NEXT_PUBLIC_* inlining doesn't reach it. We generate sw.js
* from a template at build time (Vercel/local) so the deployed file shows
* the configured brand name.
*
* Docker uses a different strategy: the builder stage exports
* NEXT_PUBLIC_BRANDING_APP_NAME=__NEXT_PUBLIC_BRANDING_APP_NAME__ so the
* placeholder survives the build, and docker-entrypoint.sh substitutes the
* runtime value via sed at container start.
*
* public/sw.js is gitignored: the source of truth is the template.
