fix: handle optional sync columns in health_source_devices

[Ricardo08S]

Summary

• Guard queries against optional Health database columns (sync_provenance, sync_identity) so the artifact works on older datasets.
• Dynamically build SELECT statements and report headers based on which columns exist, preventing SQL errors and mismatched reports.

Implementation Details

• Uses does_column_exist_in_db to detect column availability before running queries.
• Adjusts header tuples and column lookups to match the detected schema.
• Improves compatibility with both legacy and current Health databases without duplicating logic.
