/**
 * Build proxy URLs that the server's `withSigning` middleware accepts.
 *
 * Attaches the page token emitted during SSR (`_pt` + `_ts`) when one is
 * available, so client-driven proxy calls (e.g. reactive fetches, dynamic
 * image helpers exposed in slot props) authenticate without needing a
 * server round-trip to sign each URL.
 *
 * When no token is present (signing disabled or no secret), emits plain
 * `?url=...` URLs, matching the pre-signing behavior.
