OPS-REF-002B: Split PostgreSQL source-family parameter mapping

[ktalpay]

Motivation

• Reduce responsibility of postgresql_source_family_repository.py by extracting master/detail parameter mapping and JSON payload helpers into a focused module while preserving runtime orchestration in the repository.
• Make the parameter mapping reusable and easier to test without changing SQL, schema, UUID logic, or persistence behavior.

Description

• Added src/carbonfactor_parser/persistence/postgresql_source_family_parameters.py that exposes master_parameters(record), detail_parameters(record), json_payload(value), and json_safe(value) and implements the same tuple layouts and JSON conversion rules as before.
• Updated src/carbonfactor_parser/persistence/postgresql_source_family_repository.py to call master_parameters and detail_parameters and removed the previous internal helpers from the repository file, keeping orchestration, upserts, transaction helpers, and error redaction in place.
• master_parameters computes ingestion_run_uuid(record) once into ingestion_id before building the tuple to avoid repeated UUID calls while preserving deterministic behavior.
• JSON helpers preserve exact behavior: Decimal -> str, mapping keys sorted by string key, tuples/lists recursively converted to lists, and serialization uses sort_keys=True and separators=(",",":").
• Added focused tests in tests/test_postgresql_source_family_repository.py to assert master/detail tuple lengths/positions, UUID string values, compact metadata/raw/normalized JSON payloads, and json_safe behavior.

Testing

• Ran python -m pytest tests/test_postgresql_source_family_repository.py and it passed (18 passed, 1 skipped).
• Ran targeted tests python -m pytest tests/test_configured_cycle_runner.py tests/test_ingestion_run_history_mapping.py tests/test_ingestion_run_history_repository.py tests/test_ingestion_run_history_reader.py and they passed (50 passed).
• Ran the full test suite python -m pytest and it passed (2159 passed, 8 skipped).
• Ran python -m ruff check on the changed files and git diff --check, both passed.
