The requeue endpoint now handles three scenarios:
1. Original queue items still exist — uses their finding data (ideal case)
2. Queue items deleted (Clear Completed) — looks up findings from
ivanti_findings table using finding_ids_json
3. FP created outside dashboard (no queue_item_ids) — same fallback
to finding_ids_json and ivanti_findings lookup
4. Last resort — creates queue items with just finding IDs if the
findings aren't in ivanti_findings either
