* fix(proxy): strip LiteLLM policy tracking from OpenAI batch metadata Batch create was failing with `Invalid type for 'metadata.applied_policies': expected a string, but got an array instead` whenever a policy attachment matched the request. The policy engine helpers wrote `applied_policies`, `applied_guardrails`, and `policy_sources` into `data["metadata"]` unconditionally, and `/v1/batches` forwarded that dict straight to OpenAI, which only accepts string values. - Route proxy-internal tracking into `litellm_metadata` for batch/file routes via a shared `_get_or_create_proxy_metadata_bucket` helper. - Sanitize `data["metadata"]` in `create_batch` to drop known internal keys and non-string values before building the OpenAI request. - Cover both behaviors with unit + endpoint tests.
