Add a separate ClickHouse OLAP pipeline with goose/clickhouse DDL as the
sole schema source, model/analytics for ORM mapping, and repository/analytics
for reads (ChDB/GORM) and batch writes (ChConn). Refactor risk_control and
admin/logs to use the repository layer instead of inline SQL. Remove the
manual support-files DDL and document the workflow in database-migration skill.
Extract SyncEvents and InitLogWriter from router.Serve into bootstrap.Init
called from cmd entry points with trace-aware context. Preserve existing
Register* wiring for task and push domain integrations.
