fix(worker): Centralize ClickHouse configuration (fixes #286)

[stroland02]

This PR centralizes the ClickHouse connection configuration into a single module, \infra/clickhouse/config.ts. Previously, the autorecovery agent read a different database (falling back to \olly) while the primary worker and backfill scripts read from \superlog. By routing all ClickHouse connections through the same environment resolution logic, this guarantees that all modules correctly resolve the same target database, fixing Issue #286.

Summary by cubic

Centralized ClickHouse connection config in apps/worker/src/infra/clickhouse/config.ts and updated all worker components to use it. This aligns autorecovery, worker, and backfill scripts to the same DB resolution and fixes #286.

• Bug Fixes

  • Autorecovery no longer falls back to olly; all modules now read the same DB via shared envs (CLICKHOUSE_URL, CLICKHOUSE_USER, CLICKHOUSE_PASSWORD, CLICKHOUSE_DB).

• Migration

  • If you used CLICKHOUSE_DATABASE, switch to CLICKHOUSE_DB (default remains superlog).

logs · blocking — Log an error when CLICKHOUSE_DB falls back to the default in a non-local environment

Add an error-level log (using the repo's existing logger) when any of the four ClickHouse env vars is absent and the process is not running locally, so operators are immediately alerted to misconfiguration rather than discovering it through opaque query failures. Without this, a deployment that omits CLICKHOUSE_DB silently targets superlog in production with no operator-visible signal.

Suggested change

	export const CLICKHOUSE_DB = process.env.CLICKHOUSE_DB ?? "superlog";
	export const CLICKHOUSE_URL = process.env.CLICKHOUSE_URL ?? "http://localhost:8123";
	export const CLICKHOUSE_USER = process.env.CLICKHOUSE_USER ?? "default";
	export const CLICKHOUSE_PASSWORD = process.env.CLICKHOUSE_PASSWORD ?? "";
	export const CLICKHOUSE_DB = process.env.CLICKHOUSE_DB ?? "superlog";
	import { logger } from "../../logger.js";
	const _isLocal = CLICKHOUSE_URL.includes("localhost") || CLICKHOUSE_URL.includes("127.0.0.1");
	if (!_isLocal) {
	if (!process.env.CLICKHOUSE_URL) logger.error({ field: "CLICKHOUSE_URL" }, "ClickHouse config: required env var missing, using default");
	if (!process.env.CLICKHOUSE_USER) logger.error({ field: "CLICKHOUSE_USER" }, "ClickHouse config: required env var missing, using default");
	if (!process.env.CLICKHOUSE_DB) logger.error({ field: "CLICKHOUSE_DB" }, "ClickHouse config: required env var missing, using default");
	}
