fix: drop legacy app_super_admin -- SUPER_ADMIN_GROUP is now god_admin (v1.26.1)

god_admin now exists at boot (seeded by docker-entrypoint), so the canonical
cross-resource super group nested into every resource's _admin group is god_admin,
not the legacy app_super_admin. docker-entrypoint no longer seeds or nests
app_super_admin (god_admin nests into the app_sso_* groups directly). isSuperAdmin
still recognizes a pre-existing app_super_admin as a migration alias until rebuild.
