The never-activated rule left one order of events open: on an instance without SMTP, a stranger
who registered an ADMIN_EMAILS address (or a sibling spelling) and was then activated by another
admin kept their password and live session, and the owner's first Google sign-in raised that row
to admin, the stranger's cookie with it. Activation vouches for access, not for who chose the
password, and without SMTP nothing else ever proved the mailbox.
When ADMIN_EMAILS promotes an adopted account that holds a password on an instance without SMTP,
the password goes and the session epoch is bumped. With SMTP the verified flag is a proven mailbox,
and an account the sign-in does not promote keeps its password, so the "your password was cleared"
detour stays off the default path. Tests: the activated squat (red without the rule; the squatter's
session is signed out) and the SMTP case that keeps the password.
