fix: use NODE_URL env var for code browser instead of repo.nodeUrl The tree page was extracting nodeUrl from the repo record (which is null for most repos) and showing "No refs found" when it was missing. Other pages (branches, compare) already use the NODE_URL env var with a localhost fallback. Now the tree page does the same.
