Centralized path helpers for the Hello World module.
All paths go through PhoenixKit.Utils.Routes.path/1 for prefix/locale handling.
Why centralize paths?
Never hardcode URLs like "/admin/hello-world" in your LiveViews. If the
parent app changes its PhoenixKit URL prefix (e.g. /admin → /backend),
your module breaks. Using Routes.path/1 through a central Paths module
means one file to update and every navigation automatically follows.
