### Description Modernizes `ClickHouseIO` by migrating from the legacy JDBC driver (v0.6.3) to ClickHouse Java Client v2 (v0.9.6), improving performance, compatibility, and maintainability. ### Key Changes #### Core Migration: * Replaced JDBC components (`Connection`, `Statement`, `ResultSet`) with Java Client v2 APIs (`Client`, `Records`, `GenericRecord`) * Migrated from JDBC URL format to explicit clickHouseUrl, database, and table parameters #### API Enhancements: * Added new `write(String clickHouseUrl, String database, String table)` method signature * Deprecated the old `write(String jdbcUrl, String table)` method with backward compatibility * Added `ClickHouseJdbcUrlParser` utility to parse legacy JDBC URLs and maintain compatibility * Updated `withProperties()` to support property merging (new properties override existing ones) * Added deprecated overload for legacy `getTableSchema(jdbcUrl, table)` signature - that is because of the BigQuery to ClickHouse Dataflow template [usage](https://github.com/GoogleCloudPlatform/DataflowTemplates/blob/18949a0abf341da2275d5d9a5ad71e5e554da471/v2/googlecloud-to-clickhouse/src/main/java/com/google/cloud/teleport/v2/clickhouse/templates/BigQueryToClickHouse.java#L109). Backward Compatibility - No breaking changes - all existing pipelines continue to work via deprecated methods fixes #37610 ------------------------ Thank you for your contribution!
