fix: TorBox downloads stuck in 'downloading' state

Fixed race condition where TorBox reports DownloadFinished=true but
Progress < 1.0, causing IsReady() to return false and state to stay
"downloading" instead of transitioning to "pausedUP".

Also added Gitea CI workflow to push images to internal registry.

Fixes: dcy-355
