test(server): close bolt DB before TempDir cleanup (Windows unlink failure)

TestScanSummaryEnricherAdapterCarriesDeepScan passed its assertions but
failed on windows-latest: t.TempDir cleanup cannot unlink config.db
while the bbolt handle is open. setupTestStorage registers no close;
add an explicit t.Cleanup in this test's seed helper.
