cairn-mod 1.3.0

//! `tools.cairn.admin.*` handlers (§F12).
//!
//! Each endpoint lives in its own file; [`admin_router`] wires them
//! together under one `Extension<AdminState>` so sub-modules don't
//! need to duplicate state plumbing. Per-request auth + role + CORS
//! gating is centralized in the shared `common::verify_and_authorize`
//! helper inside this module.
