…rializer Replace SimpleStringSchema with a custom KafkaRecordDeserializationSchema in both normalize.py and cdc_symbol_config.py so that kafka_partition and kafka_offset written to Iceberg silver/bronze layers reflect the actual Kafka record position instead of the placeholder -1. The -1 fallback path in iceberg_reader.py is retained for backward compatibility with rows written before this fix. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

fix: store real kafka partition+offset in Iceberg via KafkaRecordDeserializer
- Add airflow/dags: backfill_ohlcv_1m, compact_iceberg_tables, expire_iceberg_snapshots, freshness_sla_check, run_dbt_models, run_great_expectations - Add spark/jobs: backfill_ohlcv, compact_tables, spark_lib - Add airflow/tests and spark/tests; include both in pytest testpaths - Rename flink/jobs/lib → flink_lib, spark/jobs/lib → spark_lib to eliminate bare `lib` package collision across services - Fix all ruff lint errors in new airflow/spark files Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
