 * concurrent `create` hit the unique email, and (b) the user — and every
 * already-minted admin token — briefly vanished. The credentials are constant
 * (testUser), so a row created by any worker is identical to the one another
 * would create: the unique-conflict loser simply proceeds, and no password
 * reset ever invalidates a live session.
