Drop dead queue-length config, controller meta, and test assertion

Step 17 residual sweep caught references the per-step grep missed:
- config/settings.yml: drop maximum_queue_number_length and the
  item_tag.default_count / default_queue_number_length keys (only
  consumed by the removed format validator and create_default_item_tags!)
- PermissionsController#index meta: drop maximum_queue_number_length
  (clients no longer need to enforce the queue-format length cap)
- permissions_controller_test: drop the matching assertion
