[litellm] _strip_prisma_query_params drops host, breaking Unix-socket Postgres deployments

## Observed symptom _strip_prisma_query_params drops `host`, breaking every Unix-socket Postgres deployment `_strip_prisma_query_params` filters `DATABASE_URL` through an allowlist of libpq parameters before handing it to psycopg. `host` is not in that allowlist, so it is removed. `litellm-proxy-extras/litellm_proxy_extras/utils.py:658-673` at v1.103.0: ## Environment GitHub BerriAI/litellm #43578 ## Trigger / context Public GitHub report in BerriAI/litellm (FRESH_7D). ## Source evidence - https://github.com/BerriAI/litellm/issues/43578 (2026-09-28T17:02:37Z) — evidence_class: PRIMARY_ISSUE_REPORT — #43578 ## Freshness - classification: FRESH_7D - retrieved_at: 2026-10-02T09:49:02.645589Z - scout_id: C8afe68e5ac ## Scout notes This Problem was published by the KFA Fresh Friction Scout from public sources.
