//! DLQ inspection mode — viewer for the worker tier's main + dead-letter
//! SQS queues with peek / delete / purge / resend flows.
//!
//! Type cluster lives here; the methods that *use* these types
//! (`spawn_dlq_fetch`, `spawn_dlq_delete_one`, `spawn_dlq_purge`,
//! `spawn_dlq_resend_selected`, `handle_dlq_key`, `open_dlq`, `close_dlq`)
//! still sit on [`crate::app::App`] because every step reaches into the
//! shared AwsClient + status toasts + audit log. Same split rationale as
//! `mode_action.rs` — types first, App-coupled handlers later if the
//! coupling can be cleanly broken.
//!
//! Types are re-exported from `crate::app` so consumers of
//! `crate::app::DlqState` / `crate::app::QueueView` keep working without
//! a sweep across the call sites.
