Paths containing (api.) are intercepted before page routing and
dispatched directly to the api function. The handler result is
rendered to SX wire format and returned without layout wrapping.
This fixes the issue where handler URLs went through page routing,
causing the handler result to be passed as a slug to the page
function, and the response to be wrapped in the full page layout.
