Add support for running Logflare in single tenant mode with ClickHouse as the backend for log ingestion. This follows the same virtual backend pattern used for PostgreSQL single tenant mode, where backend_id is nil and configuration is read from environment variables. Query/search functionality is intentionally excluded from this implementation.

Add support for running Logflare in single tenant mode with ClickHouse as the backend. This follows the same virtual backend pattern used for PostgreSQL single tenant mode, where backend_id is nil and configuration is read from environment variables.
Query/search functionality is excluded from this implementation, as bigger changes are required to support them.
