* fix(clickhouse-io): use official @clickhouse/client instead of unmaintained clickhouse package
The example imported the third-party `clickhouse` (TimonKK) package and used
its API (new ClickHouse, .query().toPromise(), .insert().stream()). Migrate to
the official @clickhouse/client: createClient() and structured
clickhouse.insert({ table, values, format }). The structured values array also
removes the previous SQL string-interpolation anti-pattern.
Applies to the source skill and the ja-JP, zh-CN, zh-TW, ko-KR translated
copies (translated code comments preserved).

* fix(clickhouse-io): migrate remaining insert calls to @clickhouse/client
Address review feedback: the earlier commit missed two spots that still used
the legacy clickhouse API.
- CDC example: clickhouse.insert('market_updates', [...]) ->
clickhouse.insert({ table, values, format: 'JSONEachRow' })
- Single-row insertTrade: map the row to the column shape (same as the bulk
path) instead of passing the raw trade object.
Applies to the source skill and the ja-JP, zh-CN, zh-TW, ko-KR copies.
