refactor: simplify order status model — remove DELIVERY_FEE_ADJUSTMENT and PAYMENT_VERIFICATION

- Add deliveryFeeLocked field to Order model
- Remove DELIVERY_FEE_ADJUSTMENT and PAYMENT_VERIFICATION statuses (11→8)
- 3 order paths: delivery+online (locked→unlocked→paid), pickup+online (unlocked→paid), pickup+on_pickup (direct to in_progress)
- Update checkout to use PENDING_PAYMENT + deliveryFeeLocked
- Update payment flow to stay in PENDING_PAYMENT until admin confirms
- Update admin UI to use deliveryFeeLocked instead of status check
- Update client payment UI with new deliveryFeeLocked logic

+# Order Status Simplification (A+B) Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Remove `DELIVERY_FEE_ADJUSTMENT` and `PAYMENT_VERIFICATION` statuses, replace with `deliveryFeeLocked` flag and simplified payment flow. Three order paths: (1) delivery+online, (2) pickup+online, (3) pickup+on_pickup.
+
+**Architecture:** Add `deliveryFeeLocked Boolean` to Order model. Path 1 (delivery+online): created as `PENDING_PAYMENT` + `deliveryFeeLocked=false`, admin approves fee → `deliveryFeeLocked=true` → client pays. Path 2 (pickup+online): created as `PENDING_PAYMENT` + `deliveryFeeLocked=true` → client pays immediately. Path 3 (pickup+on_pickup): created as `IN_PROGRESS` → no payment needed. Payment stays in `PENDING_PAYMENT` until admin confirms → `PAID`. No migration needed — no existing orders.
+
+**Tech Stack:** Prisma (SQLite), Fastify, React + MUI, TypeScript, vitest
+
+---
+
+### Task 1: Add `deliveryFeeLocked` field to Prisma schema
+
+**Files:**
+- Modify: `server/prisma/schema.prisma:124-152`
+
+- [ ] **Step 1: Add field to Order model**
+
+Add `deliveryFeeLocked Boolean @default(false)` after `status` in the `Order` model:
+
+```prisma
+model Order {
+  id                  String      @id @default(cuid())
+  status              String      @default("DRAFT")
+  deliveryFeeLocked   Boolean     @default(false)
+  /// 'delivery' | 'pickup'
+  deliveryType        String      @default("delivery")
+  // ... rest unchanged
+```
+
+- [ ] **Step 2: Run Prisma migration**
+
+```bash
+cd server && npx prisma migrate dev --name add_delivery_fee_locked
+```
+
+Expected: Migration created and applied successfully.
+
+---
+
+### Task 2: Update shared constants — remove 2 statuses
+
+**Files:**
+- Modify: `shared/constants/order-status.js`
+- Modify: `shared/constants/order-status.d.ts`
+
+- [ ] **Step 1: Write updated `order-status.js`**
+
+```js
+export const ORDER_STATUSES = Object.freeze([
+  'DRAFT',
+  'PENDING_PAYMENT',
+  'PAID',
+  'IN_PROGRESS',
+  'SHIPPED',
+  'READY_FOR_PICKUP',
+  'DONE',
+  'CANCELLED',
+])
+```
+
+- [ ] **Step 2: Write updated `order-status.d.ts`**
+
+```ts
+export declare const ORDER_STATUSES: readonly [
+  'DRAFT',
+  'PENDING_PAYMENT',
+  'PAID',
+  'IN_PROGRESS',
+  'SHIPPED',
+  'READY_FOR_PICKUP',
+  'DONE',
+  'CANCELLED',
+]
+```
+
+- [ ] **Step 3: Run client typecheck to verify no breakage**
+
+```bash
+cd client && npx tsc -b
+```
+
+Expected: No errors (other files still reference removed statuses — that's expected, they'll be fixed in later tasks).
+
+---
+
+### Task 3: Update server `canTransitionAdminOrderStatus`
+
+**Files:**
+- Modify: `server/src/lib/order-status.js`
+- Test: `server/src/lib/__tests__/order-status.test.js`
+
+- [ ] **Step 1: Write updated tests first**

+
+**Files:**
+- Modify: `server/src/routes/api/admin-orders.js`

+- [ ] **Step 1: Replace `DELIVERY_FEE_ADJUSTMENT` UI blocks**
+
+Find and replace lines 321-334:

+              <Alert severity="info">

+## Self-Review
+
+**1. Spec coverage:**
+- ✅ Remove `DELIVERY_FEE_ADJUSTMENT` — Tasks 2, 3, 4, 5, 6, 7, 8, 9, 11
+- ✅ Remove `PAYMENT_VERIFICATION` — Tasks 2, 3, 4, 6, 9, 11
+- ✅ Add `deliveryFeeLocked` field — Tasks 1, 5, 7, 8, 9, 10
+- ✅ Update checkout logic — Task 5
+- ✅ Update payment flow — Task 6
+- ✅ Update admin routes — Task 7
+- ✅ Update admin UI — Task 8
+- ✅ Update client payment UI — Task 9
+- ✅ Migrate existing data — Task 11
+
+**2. Placeholder scan:** No TBD, TODO, or incomplete sections. All steps contain actual code.
+
+**3. Type consistency:** `deliveryFeeLocked: boolean` used consistently across all files. `AdminOrderDetailResponse` and `OrderDetailResponse` both updated. All status references use the new 8-status list.

+# Дизайн: Упрощение статусной модели заказов (A+B)
+
+**Дата:** 2026-05-15
+**Статус:** Утверждено
+
+## Проблема
+
+Текущая модель заказов содержит 11 статусов, из которых два (`DELIVERY_FEE_ADJUSTMENT`, `PAYMENT_VERIFICATION`) являются промежуточными и могут быть заменены флагами/логикой.
+
+## Решение
+
+Убрать 2 статуса, добавить флаг `deliveryFeeLocked`. Итого: 9 → 8 статусов (было 11).
+
+### Удалённые статусы
+
+| Было | Чем заменяется |
+|---|---|
+| `DELIVERY_FEE_ADJUSTMENT` | Флаг `deliveryFeeLocked: Boolean` на заказе |
+| `PAYMENT_VERIFICATION` | Заказ остаётся в `PENDING_PAYMENT` до ручного подтверждения |
+
+### Новая статусная модель
+
+```

+```
+
+### Логика `deliveryFeeLocked`
+
+| Значение | Админ | Клиент |
+|---|---|---|
+| `false` | Может менять `deliveryFeeCents` | Видит "ожидает утверждения доставки", оплата недоступна |
+| `true` | Не может менять доставку | Видит кнопку оплаты |
+
+### Переходы (admin)
+
+| Из | В |
+|---|---|
+| `DRAFT` | `PENDING_PAYMENT`, `CANCELLED` |
+| `PENDING_PAYMENT` | `PAID`, `CANCELLED` |
+| `PAID` | `IN_PROGRESS`, `CANCELLED` |
+| `IN_PROGRESS` (delivery) | `SHIPPED`, `CANCELLED` |
+| `IN_PROGRESS` (pickup) | `READY_FOR_PICKUP`, `CANCELLED` |
+| `SHIPPED` | *(нет)* |
+| `READY_FOR_PICKUP` | *(нет)* |
+| `DONE` | *(нет)* |
+| `CANCELLED` | *(нет)* |
+
+### Миграция данных
+
+Все заказы в статусе `DELIVERY_FEE_ADJUSTMENT` → `PENDING_PAYMENT` + `deliveryFeeLocked: false`.
+Все заказы в статусе `PAYMENT_VERIFICATION` → `PENDING_PAYMENT`.
+
+### Изменяемые файлы
+
+1. `server/prisma/schema.prisma` — добавить `deliveryFeeLocked Boolean @default(false)`
+2. `shared/constants/order-status.js` — убрать 2 статуса
