feat(v1.1.8): admin HTTP — /apps/{id}/users + /invitations

users_admin_api router merged into the guarded admin tree at
/api/v1/admin/apps/{id_or_slug}/users/* + /invitations/*.

Endpoints (capability gates applied via the service layer):

  GET    /users                                       AppUsersRead
  GET    /users/{user_id}                             AppUsersRead
  POST   /users                                       AppUsersWrite
  PATCH  /users/{user_id}                             AppUsersWrite
  DELETE /users/{user_id}                             AppUsersWrite (admins satisfy implicitly)
  POST   /users/{user_id}/reset-password              AppUsersAdmin -> one-shot token
  POST   /users/{user_id}/revoke-sessions             AppUsersAdmin
  GET    /invitations                                 AppUsersAdmin
  POST   /invitations                                 AppUsersAdmin
  DELETE /invitations/{invite_id}                     AppUsersAdmin

DTOs never include password_hash, session tokens, or unrotated
reset tokens. The reset-password endpoint returns the raw one-shot
token exactly once in the response body so an admin can paste it
into a manual reset link (TTL 1h by default).

Synth_cx() factors the admin-side cx construction into one place
(marked) so the SDK and admin code paths share the service's authz
fan-out. Admin-mediated trait methods (admin_create_invitation,
admin_reset_password_token, admin_revoke_all_sessions,
list_invitations, revoke_invitation) take &Principal directly,
not the synthesized cx.

UsersServiceImpl: removed the NOT_YET_IMPL constant + unused
auth alias (every method has a real implementation now). Added
Serialize+Deserialize on the AppUser / Invitation shared DTOs so
the admin HTTP layer doesn't need a parallel set of types.

+//! `/api/v1/admin/apps/{id_or_slug}/users/*` + `/invitations/*` —
+//! admin HTTP surface for v1.1.8 user management.
+//!
+//! All endpoints are capability-gated against the resolved
+//! `app_id` (extracted from the path then validated via the apps
+//! repo — never trusted at face value). Read vs Write vs Admin
+//! mirrors the SDK's gating from the brief.

+//! No DTO ever returns a password hash, a session token, or a long-

+//! `POST /users/{user_id}/reset-password` which returns the one-shot
+//! reset token in its body so an admin can paste it into a manual
