/**
 * Approval demo bootstrap — makes the marquee v16 approval features
 * (M-of-N quorum + per-group 会签, server-computed progress, decision
 * attachments, `?request=` deep links, viewer gating, the reassign picker)
 * demonstrable on a FRESH boot, with no manual setup.
 *
 * Why this exists (and can't be a seed):
 *  - The `approval` flow nodes route to `{ type: 'position', value: 'finance' |
 *    'legal' | 'manager' }`. Approver resolution reads `sys_user_position`
 *    (ADR-0090 D3), but users can't be seeded (they sign up) and position
 *    assignments are runtime admin actions — so out of the box NO ONE holds
 *    those positions and every request resolves to an empty slate and waits
 *    forever.
 *  - The seed loader SUPPRESSES record-change flows (#2661), so seeding an
 *    invoice as `sent` (or an expense as `submitted`) never opens a request.
 *  - `sys_approval_request` is engine-owned (ADR-0103: get/list only), so a
 *    request can't be inserted through the generic data API either.
 *
 * So we play the admin's part imperatively, exactly like `bind-position-sets.ts`:
 * on `kernel:bootstrapped` (after the security bootstrap has created the
 * position/permission rows and the automation engine is wired) we
 *   1. assign the dev-seeded admin to `manager` / `finance` / `legal` so they
 *      are a resolvable approver on every demo request (and can act in the
 *      inbox);
 *   2. provision a phone-based demo user so the "phone sign-in surfaces" show
 *      a real number in the All Users list + record detail;
 *   3. launch the Invoice Dual Sign-off (finance ∧ legal — 会签) and the
 *      High-Value Committee Quorum (2-of-3) flows through the real automation
 *      engine, so genuine, resumable pending requests land in the inbox.
 *
 * Everything is idempotent: a persistent DB keeps the assignments/requests, and
 * `openNodeRequest` rejects a duplicate pending request per (object, record),
 * which we swallow.
