// #3368 PR6 — web-session (cookie) bulk import must dedupe credentials.
// Re-importing the same cookie/token (even under a different name) must UPDATE
// the existing connection, not insert a duplicate row — mirroring the apikey
// dedup behavior (#3023). This test fails before the cookie-dedup branch exists.
