Pouzor 7608d07255 fix: flush before reading node IDs in bulk/single approve; 404/409 guards; catch scan errors
- db.flush() ensures node.id is populated before reading — fixes bulk approve
  where node_ids were null, causing frontend to skip addNode for every device
- approve_device raises 404 on missing device, 409 on already-processed device
- _background_scan rollbacks dirty session then marks run as "failed"
- Explicit Node() field mapping instead of **model_dump() to prevent injection
- update_scan_config rolls back in-memory change if save_overrides() fails
- clear_pending uses bulk DELETE instead of N individual row deletes
