fix(settings): correct invoke payload keys and error handler routing

- folder_ids: use snake_case in both set_tagging_queue_folder_ids invoke
  calls (toggleTaggingQueueFolder and setTaggingQueueFolderIds) to match
  the Rust SetTaggingQueueFolderIdsParams serde field name
- threshold save error: route setTaggerThreshold() catch to
  setTaggerThresholdError instead of setTaggerQueueStatus so the error
  surfaces next to the threshold input, not the queue targets card
