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.

+# v1.26.1
+- fix: the legacy `app_super_admin` group is gone — `SUPER_ADMIN_GROUP` (nested into every resource's `_admin` group by auto-provisioning) is now `god_admin`, and `docker-entrypoint.sh` no longer seeds or nests `app_super_admin` (god_admin is nested into the `app_sso_*` groups directly). `isSuperAdmin` still recognizes a pre-existing `app_super_admin` as a migration alias, so an old deployment isn't stripped of rights until it's rebuilt.

 # v1.26.0
 - feat: complete the group model (docs/GROUPS.md) — `god_admin` is now seeded into LDAP and nested into `app_super_admin`; every site auto-provisions `{site}_super_admin`, `{site}_hosts_*`/`{site}_apps_*` aggregates and `{site}_everyone`; per-resource `_admin`/`_access` groups (named `{site}_{slug}_{level}`, the kind carried in the resource slug) are nested into the site aggregates so the inheritance lattice exists in LDAP, not just in the resolver. Site/aggregate groups are self-healed idempotently on every Directory load, so a directory seeded by an older release picks them up without a rebuild.
 - feat: the naming convention is now enforced server-side — `POST /api/directory-admin/groups` rejects a group CN that isn't a valid group for the target resource (its own `_admin`/`_access`/capability, a site aggregate, a site-level group, or `god_admin`), so the free-text field can no longer mint `*_accessmember`-style names
