## Context
Self-hosting Helicone locally: the service URL for that host and port unreachable; the clickhouse-migration-runner exits with `SyntaxError: EOL while scanning string literal` at `curl_cmd = f"cat \"{migration_file}\" | curl '{ ...` in ch_hcone.py.

## Verified resolution
Resolved by a community member (tscodeler): the multi-line f-string in `ch_hcone.py`'s run_curl_command is broken in the local checkout, fix the string formatting in that function so the curl command is a single valid f-string, and add the MINIO env vars to the docker .env file (MINIO_ROOT_USER and MINIO_ROOT_PASSWORD). Maintainer connortbot later closed it noting the self-hosting docs were reworked: current flow is `./helicone_compose up helicone` per https://docs.helicone.ai/getting-started/self-host/docker.
