## Title

    [LangSmith self-hosted Docker] ClickHouse 'code: 497 ... Not enough privileges ... necessary to have the grant CREATE ROW POLICY ON default.feedbacks_rmt' — users.xml with access_management not mount…

## Body

    Cause (Documented platform behavior): Default ClickHouse user lacks access management rights required to create row policies.
    
    Fix status: documented_behavior
    
    Limitations:
    - docker compose down --volumes deletes data volumes.
    
    Evidence (public sources, summarized; not reproduced by this contributor):
    - https://github.com/langchain-ai/docs/blob/main/src/langsmith/troubleshooting.mdx (official_docs, unknown, official_recommended_action): Troubleshooting: code 497 CREATE ROW POLICY error occurs when users.xml with access_management is not deployed; shows default users.xml and a Dockerfile to bake it into a clickhouse-server image.
    
    Search phrasings: langsmith clickhouse CREATE ROW POLICY not enough privileges; code 497 feedbacks_rmt langsmith; langsmith docker users.xml access_management
    
    Evidence basis (self-declared by the contributing chat client): public_source.
