    * Normalizes HTTP URI by removing duplicate slashes while preserving the protocol part.
    * 
    * This function removes consecutive forward slashes from URIs while keeping the protocol 
    * section (http:// or https://) intact. It processes everything after the protocol to 
    * ensure clean URI formatting.
    *
    * @param uri The input URI string to be normalized
    * @return A normalized URI string with duplicate slashes removed, or the original 
    *         string if it's empty
    *
    * @example
    *   normalize_http_uri("https://example.com//path//to///file") 
    *   returns "https://example.com/path/to/file"
    *
    *   normalize_http_uri("http://host.com///bucket//prefix/") 
    *   returns "http://host.com/bucket/prefix/"
    *
    *   normalize_http_uri("endpoint.com//bucket///prefix") 
    *   returns "endpoint.com/bucket/prefix"
    *
    *   normalize_http_uri("https://account.blob.core.windows.net////container") 
    *   returns "https://account.blob.core.windows.net/container"
