Fix: persist catalog classification to DB after GPN failure. Previously, reclassifyDeviceFromCatalog was called but the result was not saved (first persist happened before catalog call). Now: setUnsupported → recordFailure → reclassify via catalog → persist (single createOrUpdate with full snapshot including classified params). All 811 tests pass. Build status: Success
