/**
 * @fileoverview Approvals Inbox UI: cross-session queue of prompts waiting on a human.
 *
 * Everything here is gated on the OPT-IN `approvalsInboxEnabled` setting
 * (synced, default OFF): with it off, no bell, no drawer, no overview strips,
 * no seeding. When on, the header bell renders only while items are pending
 * (count badge), opening a right-side drawer of approval cards; pending items
 * are seeded from `GET /api/approvals` on init/reconnect (so tab alerts
 * survive a reload) and answered in place via `POST /api/approvals/:id/answer`. Cards render
 * buttons from the server-parsed dialog options; without parsed options they
 * fall back to Approve/Deny (permission/question) or a text prompt (idle).
 * Backend: src/web/approval-inbox.ts, design: docs/approvals-inbox-plan.md.
 *
 * @mixin Extends CodemanApp.prototype via Object.assign
 * @dependency app.js (CodemanApp class, this.approvals, setPendingHook/clearPendingHooks, selectSession)
 * @dependency constants.js (escapeHtml)
 * @dependency api-client.js at runtime (this._apiJson; loads later but is only called after init)
 * @loadorder 11.6 of 17, after ultracode-panel.js, before admin-ui.js
