fix(prometheus): route litellm_callback_logging_failures_metric through get_labels_for_metric

Browse source 
The metric was registered with hardcoded labelnames=["callback_name"] instead of
going through get_labels_for_metric(), so prometheus_exclude_labels had no effect
on it. Route through get_labels_for_metric() and wrap the observation site with
_safe_labels() for consistency.
