Rotation is optional now, so a well-known default ('clusev') would be a standing takeover
credential on a fleet-root console. The installer now creates the first admin with a random
Str::password(16), printed once on the CLUSEV_ADMIN_PASSWORD= line that install.sh already
surfaces in the closing banner. must_change_password still nudges a rotation, but even if the
operator keeps it, the secret is no longer guessable.
Verified: the printed password authenticates + differs per install; noop-when-admin-exists is
intact; Codex review APPROVED.
