Raw byte replacement in _merge_helm_indexes only worked when the upstream
index contained absolute URLs matching base_url. Upstreams like Rancher use
relative URLs (e.g. rancher-2.13.1.tgz), which were left unrewritten,
causing Helm to construct a 404-producing URL against the virtual repo.

Now parses YAML first, then rewrites each entry's urls list:
- relative URL → prepend {proxy_base}/api/v1/remote/{member_name}/
- absolute URL matching base_url → replace prefix with proxy remote path
