Function runtime_public_site_origins_with 

pub fn runtime_public_site_origins_with<F>(
    value: Option<&str>,
    on_invalid: F,
) -> Vec<String>
where
    F: FnMut(Option<&str>, &UtilsError),

Parses runtime public-site origins, ignoring invalid entries individually.

The on_invalid callback receives invalid entries or whole-value parse failures so product crates can log with their own config key and context.
