/**
 * Fetch the absolute filesystem path of a song from Navidrome's native API.
 * Subsonic `getSong.view` only returns a relative path (or none on Navidrome);
 * the native `/api/song/:id` endpoint returns the absolute path the server
 * stores the file at, the same way Feishin and the Navidrome web client get it.
 *
 * Returns `null` when the server doesn't expose the field (non-admin on some
 * Navidrome configurations) or when the call fails — the Song Info modal then
 * falls back to whatever the Subsonic response had.
