fix(release): make the packaged-app smoke open the database before asserting the SQLite driver

The packaged app opens SQLite lazily and the smoke's readiness URL (/login) never
touches it, so the logs carried no "[DB] Driver: ..." line and
assertNativeDriverSelected failed on the v3.8.50 re-attach (run 33251755872) with
every leg green up to that point — the assertion could not distinguish a native
driver from no database at all. After readiness the smoke now requests
/api/monitoring/health (DB-backed) and waits up to 15 s for the driver line; the
cold-restart assertion is unchanged. Unit tests cover the wait and the timeout.
