fix: use shared httpx transport and remove unused TICKERR_CLIENT_TIER

- Replace raw urllib.request with litellm's _get_httpx_client() to
  follow the repo's shared HTTP layer policy
- Remove TICKERR_CLIENT_TIER from callback_configs.json since the
  code never reads it and we don't need to collect tier data
