Local toggle_play always called resume(), which fails with "cannot resume -
no audio data available" when the player holds no loaded stream — e.g. a
freshly materialized QConnect renderer queue whose cursor sits on a track that
was never loaded. Detect the no-loaded-audio case via Player::has_loaded_audio()
and load+play the current queue track instead of resuming. A normal pause keeps
the stream loaded, so the pause/resume path is unchanged.
