Return a single track the caller may access (they created it or saved it) plus freshly-minted short-TTL signed playback URLs for the master and any stems.
URLs are minted on each request and expire quickly. Returns 404 if the track does not exist or the caller has no access to it (IDOR-safe — the same response for both cases).

Id of the track (mtrack_-prefixed).
A track object with freshly-minted signed playback URL(s).
