Fix a repo link Gitea serves at a different path

The footer built `${REPO_URL}/blob/main/LICENSE` by hand. Gitea serves files
at /src/branch/<ref>/, not GitHub's /blob/<ref>/, and both hosts 200 on the repo
root — so the link read fine in review and 404s only when clicked. That is
exactly how it survived the move.

There is now one `repoFile()` helper, so a single place knows the shape.
Every repo link in the built output was resolved against the live Gitea
instance: both 200.
