Previously, the discovery endpoint always used HTTPS due to relying on SWD.url_builder, which in turn used URI::HTTPS to build the URI, supporting only the HTTPS scheme. This change enables HTTP URLs to work correctly by using URI::Generic.build instead, preserving the original scheme.
Store the original scheme from the input URI.
Use URI::Generic.build instead of SWD.url_builder/URI::HTTPS.
