* fix(proxy): keep deployment labels on cache-hit post_call rejections
A post-call failure on a response served from the litellm cache set no first_api_call_start_time, so the failure hook flagged it as rejected before routing and dropped the model_id and provider labels

* fix(proxy): read the cache hit from caching_details in the failure hook
model_call_details[cache_hit] is stamped inside the enqueued success handler, so a post-call failure can observe it too early; logging_obj.caching_details is set synchronously before the cached response returns
