Adds an authenticated admin surface gated by auth.users.app_metadata.role==='admin'. - lib/auth/admin-guard.ts: requireAdmin() (pages) + requireAdminApi() (routes) - middleware.ts: defense-in-depth /admin and /api/admin guarding - API: users (list/detail/role/ban/delete), tunnels (list + active/quota/reset/reassign/regenerate-token/delete), metrics, audit log, reserved subdomains - Self-lockout prevention (no self demote/ban/delete) - Best-effort Redis kill-switch via dependency-free net-socket client (REDIS_URL) - admin_audit_log + reserved_subdomains migration (RLS on, service-role only) - Admin UI (overview, users, tunnels, reserved, audit) + conditional nav link
