Fixes the root cause of the regression from v1.7.16. The v1.7.16 fix
correctly cast arrQueueId to String, but the lookup was performed
against downloadClientRegistry.getAllDownloads() which returns raw
download client data (qBittorrent, SABnzbd, etc.) that never has
arrQueueId populated.
The fix now looks up the queue record directly from the Sonarr/Radarr
queue cache where record.id is the numeric queue ID, using String()
casting on both sides to handle the DOM-dataset (string) vs API
response (number) type difference.
