feat(clickhouse): add write-path, DDL, and probe metrics (#776)

* feat(clickhouse): add write-path, DDL, and probe metrics

Adds seven metrics for the ClickHouse destination.

Write path:
- etl_clickhouse_insert_rows
- etl_clickhouse_insert_bytes
- etl_clickhouse_insert_errors_total
- etl_clickhouse_statements_per_batch

DDL:
- etl_clickhouse_ddl_errors_total

Probes:
- etl_clickhouse_connectivity_check_duration_seconds
- etl_clickhouse_schema_query_duration_seconds

METRICS.md documents the full set and how to read each metric.

* feat(clickhouse): add insert encoding-error counter

Adds etl_clickhouse_insert_encoding_errors_total to track rows rejected
by RowBinary encoding before any network round-trip. Pairs with
etl_clickhouse_insert_errors_total, which continues to count only
INSERT round-trip failures.
