pricing: enrich pricelist items with stock and tighten CORS

- Remove unused stockMappingsCache variable (dead code after selectStockMappingRow removal)
- Move data-description from SVG to button element for reliable access
- Add disabled guard on bulk add/ignore buttons to prevent duplicate requests
- Return explicit error in UpsertIgnoreRule when rule already exists

 # QuoteForge - Claude Code Instructions
 
 ## Overview
-Корпоративный конфигуратор серверов и формирование КП. MariaDB (RFQ_LOG) + SQLite для оффлайн.
+Корпоративный конфигуратор серверов с offline-first архитектурой.
+Приложение работает через локальную SQLite базу, синхронизация с MariaDB выполняется фоново.
 
-## Development Phases
+## Product Scope
+- Конфигуратор компонентов и расчёт КП
+- Проекты и конфигурации
+- Read-only просмотр прайслистов из локального кэша
+- Sync (pull компонентов/прайслистов, push локальных изменений)
 
-### Phase 1: Pricelists in MariaDB ✅ DONE
+Из области исключены:
-### Phase 2: Local SQLite Database ✅ DONE
+- admin pricing UI/API
+- stock import
+- alerts
+- cron/importer утилиты
 
-### Phase 2.5: Full Offline Mode 🔶 IN PROGRESS
+## Architecture
-**Local-first architecture:** приложение ВСЕГДА работает с SQLite, MariaDB только для синхронизации.
+- Local-first: чтение и запись происходят в SQLite
+- MariaDB используется как сервер синхронизации
+- Background worker: периодический sync push+pull
 
-**Принцип работы:**
+## Guardrails
-- ВСЕ операции (CRUD) выполняются в SQLite
+- Не возвращать в проект удалённые legacy-разделы: cron jobs, importer utility, admin pricing, alerts, stock import.
-- При создании конфигурации:
+- Runtime-конфиг читается из user state (`config.yaml`) или через `-config` / `QFS_CONFIG_PATH`; не хранить рабочий `config.yaml` в репозитории.
-  1. Если online → проверить новые прайслисты на сервере → скачать если есть
+- `config.example.yaml` остаётся единственным шаблоном конфигурации в репо.
-  2. Далее работаем с local_pricelists (и online, и offline одинаково)
+- Любые изменения в sync должны сохранять local-first поведение: локальные CRUD не блокируются из-за недоступности MariaDB.
-- Background sync: push pending_changes → pull updates
 
-**DONE:**
+## Key SQLite Data
-- ✅ Sync queue table (pending_changes) - `internal/localdb/models.go`
+- `connection_settings`
-- ✅ Model converters: MariaDB ↔ SQLite - `internal/localdb/converters.go`
+- `local_components`
-- ✅ LocalConfigurationService: все CRUD через SQLite - `internal/services/local_configuration.go`
+- `local_pricelists`, `local_pricelist_items`
-- ✅ Pre-create pricelist check: `SyncPricelistsIfNeeded()` - `internal/services/sync/service.go`
+- `local_configurations`
-- ✅ Push pending changes: `PushPendingChanges()` - sync service + handlers
+- `local_projects`
-- ✅ Sync API endpoints: `/api/sync/push`, `/pending/count`, `/pending`
+- `pending_changes`
-- ✅ Integrate LocalConfigurationService in main.go (replace ConfigurationService)
-- ✅ Add routes for new sync endpoints (`/api/sync/push`, `/pending/count`, `/pending`)
-- ✅ ConfigurationGetter interface for handler compatibility
-- ✅ Background sync worker: auto-sync every 5min (push + pull) - `internal/services/sync/worker.go`
-- ✅ UI: sync status indicator (pending badge + sync button + offline/online dot) - `web/templates/partials/sync_status.html`
-- ✅ RefreshPrices for local mode:
-  - `RefreshPrices()` / `RefreshPricesNoAuth()` в `local_configuration.go`
-  - Берёт цены из `local_components.current_price`
-  - Graceful degradation при отсутствии компонента
-  - Добавлено поле `price_updated_at` в `LocalConfiguration` (models.go:72)
-  - Обновлены converters для PriceUpdatedAt
-  - UI кнопка "Пересчитать цену" работает offline/online
-- ✅ Fixed sync bugs:
-  - Duplicate entry error при update конфигураций (`sync/service.go:334-365`)
-  - pushConfigurationUpdate теперь проверяет наличие server_id перед update
-  - Если нет ID → получает из LocalConfiguration.ServerID или ищет на сервере
-  - Fixed setup.go: `settings.Password` → `settings.PasswordEncrypted`
-
-**TODO:**
-- ❌ Conflict resolution (Phase 4, last-write-wins default)
-
-### UI Improvements ✅ MOSTLY DONE
-
-**1. Sync UI + pricelist badge: ✅ DONE**
-- ✅ `sync_status.html`: SVG иконки Online/Offline (кликабельные → открывают модал)
-- ✅ Кнопка sync → иконка circular arrows (только full sync)
-- ✅ Модальное окно "Статус системы" в `base.html` (info о БД, ошибки синхронизации)
-- ✅ `configs.html`: badge с версией активного прайслиста
-- ✅ Загрузка через `/api/pricelists/latest` при DOMContentLoaded
-- ✅ Удалён dropdown с Push changes (упрощение UI)
-
-**2. Прайслисты → вкладка в "Администратор цен": ✅ DONE**
-- ✅ `base.html`: убрана ссылка "Прайслисты" из навигации
-- ✅ `admin_pricing.html`: добавлена вкладка "Прайслисты"
-- ✅ Логика перенесена из `pricelists.html` (table, create modal, CRUD)
-- ✅ Route `/pricelists` → редирект на `/admin/pricing?tab=pricelists`
-- ✅ Поддержка URL param `?tab=pricelists`
-
-**3. Модал "Настройка цены" - кол-во котировок с учётом периода: ❌ TODO**
-- Текущее: показывает только общее кол-во котировок
-- Новое: показывать `N (всего: M)` где N - за выбранный период, M - всего
-- ❌ `admin_pricing.html`: обновить `#modal-quote-count`
-- ❌ `admin_pricing_handler.go`: в `/api/admin/pricing/preview` возвращать `quote_count_period` + `quote_count_total`
-
-**4. Страница настроек: ❌ ОТЛОЖЕНО**
-- Перенесено в Phase 3 (после основных UI улучшений)
-
-### Phase 3: Projects and Specifications
-- qt_projects, qt_specifications tables (MariaDB)
-- Replace qt_configurations → Project/Specification hierarchy
-- Fields: opty, customer_requirement, variant, qty, rev
-- Local projects/specs with server sync
-
-### Phase 4: Price Versioning
-- Bind specifications to pricelist versions
-- Price diff comparison
-- Auto-cleanup expired pricelists (>1 year, usage_count=0)
-
-## Tech Stack
-Go 1.22+ | Gin | GORM | MariaDB 11 | SQLite (glebarez/sqlite) | htmx + Tailwind CDN | excelize
-
-## Key Tables
-
-### READ-ONLY (external systems)
-- `lot` (lot_name PK, lot_description)
-- `lot_log` (lot, supplier, date, price, quality, comments)
-- `supplier` (supplier_name PK)
-
-### MariaDB (qt_* prefix)
-- `qt_lot_metadata` - component prices, methods, popularity
-- `qt_categories` - category codes and names
-- `qt_pricelists` - version snapshots (YYYY-MM-DD-NNN format)
-- `qt_pricelist_items` - prices per pricelist
-- `qt_projects` - uuid, opty, customer_requirement, name (Phase 3)
-- `qt_specifications` - project_id, pricelist_id, variant, rev, qty, items JSON (Phase 3)
-
-### SQLite (data/quoteforge.db)
-- `connection_settings` - encrypted DB credentials (PasswordEncrypted field)
-- `local_pricelists/items` - cached from server
-- `local_components` - lot cache for offline search (with current_price)
-- `local_configurations` - UUID, items, price_updated_at, sync_status (pending/synced/conflict), server_id
-- `local_projects/specifications` - Phase 3
-- `pending_changes` - sync queue (entity_type, uuid, op, payload, created_at, attempts, last_error)
-
-## Business Logic
-
-**Part number parsing:** `CPU_AMD_9654` → category=`CPU`, model=`AMD_9654`
-
-**Price methods:** manual | median | average | weighted_median
-
-**Price freshness:** fresh (<30d, ≥3 quotes) | normal (<60d) | stale (<90d) | critical
-
-**Pricelist version:** `YYYY-MM-DD-NNN` (e.g., `2024-01-31-001`)

-# Local-First Architecture Integration Guide
-
-## Overview
-
-QuoteForge теперь поддерживает local-first архитектуру: приложение ВСЕГДА работает с SQLite (localdb), MariaDB используется только для синхронизации.
-
-## Реализованные компоненты
-
-### 1. Конвертеры моделей (`internal/localdb/converters.go`)
-
-Конвертеры между MariaDB и SQLite моделями:
-- `ConfigurationToLocal()` / `LocalToConfiguration()`
-- `PricelistToLocal()` / `LocalToPricelist()`
-- `ComponentToLocal()` / `LocalToComponent()`
-
-### 2. LocalDB методы (`internal/localdb/localdb.go`)
-
-Добавлены методы для работы с pending changes:
-- `MarkChangesSynced(ids []int64)` - помечает изменения как синхронизированные
-- `GetPendingCount()` - возвращает количество несинхронизированных изменений
-
-### 3. Sync Service расширения (`internal/services/sync/service.go`)
-
-Новые методы:
-- `SyncPricelistsIfNeeded()` - проверяет и скачивает новые прайслисты при необходимости
-- `PushPendingChanges()` - отправляет все pending changes на сервер
-- `pushSingleChange()` - обрабатывает один pending change
-- `pushConfigurationCreate/Update/Delete()` - специфичные методы для конфигураций
-
-**ВАЖНО**: Конструктор изменен - теперь требует `ConfigurationRepository`:
-```go
-syncService := sync.NewService(pricelistRepo, configRepo, local)
-```
-
-### 4. LocalConfigurationService (`internal/services/local_configuration.go`)
-
-Новый сервис для работы с конфигурациями в local-first режиме:
-- Все операции CRUD работают через SQLite
-- Автоматически добавляет изменения в pending_changes
-- При создании конфигурации (если online) проверяет новые прайслисты
-
-```go
-localConfigService := services.NewLocalConfigurationService(
-    localDB,
-    syncService,
-    quoteService,
-    isOnlineFunc,
-)
-```
-
-### 5. Sync Handler расширения (`internal/handlers/sync.go`)
-
-Новые endpoints:
-- `POST /api/sync/push` - отправить pending changes на сервер
-- `GET /api/sync/pending/count` - получить количество pending changes
-- `GET /api/sync/pending` - получить список pending changes
-
-## Интеграция
-
-### Шаг 1: Обновить main.go
-
-```go
-// В cmd/qfs/main.go
-syncService := sync.NewService(pricelistRepo, configRepo, local)
-
-// Создать isOnline функцию
-isOnlineFunc := func() bool {
-    sqlDB, err := db.DB()
-    if err != nil {
-        return false
-    }
-    return sqlDB.Ping() == nil
-}
-
-// Создать LocalConfigurationService
-localConfigService := services.NewLocalConfigurationService(
-    local,
-    syncService,
-    quoteService,
-    isOnlineFunc,
-)
-```
-
-### Шаг 2: Обновить ConfigurationHandler
-
-Заменить `ConfigurationService` на `LocalConfigurationService` в handlers:
-
-```go
-// Было:
-configHandler := handlers.NewConfigurationHandler(configService, exportService)
-
-// Стало:
-configHandler := handlers.NewConfigurationHandler(localConfigService, exportService)
-```
-
-### Шаг 3: Добавить endpoints для sync
-
-В роутере добавить:
-```go
-syncGroup := router.Group("/api/sync")
-{
-    syncGroup.POST("/push", syncHandler.PushPendingChanges)
-    syncGroup.GET("/pending/count", syncHandler.GetPendingCount)
-    syncGroup.GET("/pending", syncHandler.GetPendingChanges)
-}
-```
-
-## Как это работает
-
-### Создание конфигурации
-
-1. Пользователь создает конфигурацию
-2. `LocalConfigurationService.Create()`:
-   - Если online → `SyncPricelistsIfNeeded()` проверяет новые прайслисты
-   - Сохраняет конфигурацию в SQLite
-   - Добавляет в `pending_changes` с operation="create"
-3. Конфигурация доступна локально сразу
-
-### Синхронизация с сервером
-
-**Manual sync:**
-```bash
-POST /api/sync/push
-```
-
-**Background sync (TODO):**
-- Периодический worker вызывает `syncService.PushPendingChanges()`
-- Проверяет online статус
-- Отправляет все pending changes на сервер
-- Удаляет успешно синхронизированные записи
-
-### Offline режим
-
-1. Все операции работают нормально через SQLite
-2. Изменения копятся в `pending_changes`
-3. При восстановлении соединения автоматически синхронизируются
-
-## Pending Changes Queue
-
-Таблица `pending_changes`:
-```go
-type PendingChange struct {
-    ID         int64     // Auto-increment
-    EntityType string    // "configuration", "project", "specification"
-    EntityUUID string    // UUID сущности
-    Operation  string    // "create", "update", "delete"
-    Payload    string    // JSON snapshot сущности
-    CreatedAt  time.Time
-    Attempts   int       // Счетчик попыток синхронизации
-    LastError  string    // Последняя ошибка синхронизации
-}
-```
-
-## TODO для Phase 2.5
-
-- [ ] Background sync worker (автоматическая синхронизация каждые N минут)
-- [ ] Conflict resolution (при конфликтах обновления)
-- [ ] UI: pending counter в header
-- [ ] UI: manual sync button
-- [ ] UI: conflict alerts
-- [ ] Retry logic для failed pending changes
-- [ ] RefreshPrices для local mode (через local_components)
-
-## Testing
-
-```bash
-# Compile
-go build ./cmd/qfs
-
-# Run
-./quoteforge
-
-# Check pending changes
-curl http://localhost:8080/api/sync/pending/count
-
-# Manual sync
-curl -X POST http://localhost:8080/api/sync/push

-# Миграция: Функционал пересчета цен в конфигураторе
-
-## Описание изменений
-
-Добавлен функционал автоматического обновления цен компонентов в сохраненных конфигурациях.
-
-### Новые возможности
-
-1. **Кнопка "Пересчитать цену"** на странице конфигуратора
-   - Обновляет цены всех компонентов в конфигурации до актуальных значений из базы данных
-   - Сохраняет количество компонентов, обновляя только цены
-   - Отображает время последнего обновления цен
-
-2. **Поле `price_updated_at`** в таблице конфигураций
-   - Хранит дату и время последнего обновления цен
-   - Отображается на странице конфигуратора в удобном формате ("5 мин. назад", "2 ч. назад" и т.д.)
-
-### Изменения в базе данных
-
-Добавлено новое поле в таблицу `qt_configurations`:
-```sql
-ALTER TABLE qt_configurations
-ADD COLUMN price_updated_at TIMESTAMP NULL DEFAULT NULL
-AFTER server_count;
-```
-
-### Новый API endpoint
-
-```
-POST /api/configs/:uuid/refresh-prices
-```
-
-**Требования:**
-- Авторизация: Bearer Token
-- Роль: editor или выше
-
-**Ответ:**
-```json
-{
-  "id": 1,
-  "uuid": "...",
-  "name": "Конфигурация 1",
-  "items": [
-    {
-      "lot_name": "CPU_AMD_9654",
-      "quantity": 2,
-      "unit_price": 11500.00
-    }
-  ],
-  "total_price": 23000.00,
-  "price_updated_at": "2026-01-31T12:34:56Z",
-  ...
-}
-```
-
-## Применение изменений
-
-### 1. Обновление базы данных
-
-Запустите сервер с флагом миграции:
-```bash
-./quoteforge -migrate -config config.yaml
-```
-
-Или выполните SQL миграцию вручную:
-```bash
-mysql -u user -p RFQ_LOG < migrations/004_add_price_updated_at.sql
-```
-
-### 2. Перезапуск сервера
-
-После применения миграции перезапустите сервер:
-```bash
-./quoteforge -config config.yaml
-```
-
-## Использование
-
-1. Откройте любую сохраненную конфигурацию в конфигураторе
-2. Нажмите кнопку **"Пересчитать цену"** рядом с кнопкой "Сохранить"
-3. Все цены компонентов будут обновлены до актуальных значений
-4. Конфигурация автоматически сохраняется с обновленными ценами
-5. Под кнопками отображается время последнего обновления цен
-
-## Технические детали
-
-### Измененные файлы
-
-- `internal/models/configuration.go` - добавлено поле `PriceUpdatedAt`
-- `internal/services/configuration.go` - добавлен метод `RefreshPrices()`
-- `internal/handlers/configuration.go` - добавлен обработчик `RefreshPrices()`
-- `cmd/qfs/main.go` - добавлен маршрут `/api/configs/:uuid/refresh-prices`
-- `web/templates/index.html` - добавлена кнопка и JavaScript функции
-- `migrations/004_add_price_updated_at.sql` - SQL миграция
-- `CLAUDE.md` - обновлена документация
-
-### Логика обновления цен
-
-1. Получение конфигурации по UUID
-2. Проверка прав доступа (пользователь должен быть владельцем)
-3. Для каждого компонента в конфигурации:
-   - Получение актуальной цены из `qt_lot_metadata.current_price`
-   - Обновление `unit_price` в items
-4. Пересчет `total_price` с учетом `server_count`
-5. Установка `price_updated_at` на текущее время
-6. Сохранение конфигурации
-
-### Обработка ошибок
-
-- Если компонент не найден или у него нет цены - сохраняется старая цена
-- При ошибках доступа возвращается 403 Forbidden
-- При отсутствии конфигурации возвращается 404 Not Found
-
-## Отмена изменений (Rollback)
-
-Для отмены миграции выполните:
-```sql
-ALTER TABLE qt_configurations DROP COLUMN price_updated_at;
-```
-
-**Внимание:** После отмены миграции функционал пересчета цен перестанет работать корректно.

-## Cron Jobs
-
-QuoteForge now includes automated cron jobs for maintenance tasks. These can be run using the built-in cron functionality in the Docker container.
-
-### Docker Compose Setup
-
-The Docker setup includes a dedicated cron service that runs the following jobs:
-
-- **Alerts check**: Every hour (0 * * * *)
-- **Price updates**: Daily at 2 AM (0 2 * * *)
-- **Usage counter reset**: Weekly on Sunday at 1 AM (0 1 * * 0)
-- **Popularity score updates**: Daily at 3 AM (0 3 * * *)
-
-To enable cron jobs in Docker, run:
-
-```bash
-docker-compose up -d
-```
-
-### Manual Cron Job Execution
-
-You can also run cron jobs manually using the quoteforge-cron binary:
-
-```bash
-# Check and generate alerts
-go run ./cmd/cron -job=alerts
-
-# Recalculate all prices
-go run ./cmd/cron -job=update-prices
-
-# Reset usage counters
-go run ./cmd/cron -job=reset-counters
-
-# Update popularity scores
-go run ./cmd/cron -job=update-popularity
-```
-
-### Cron Job Details
-
-- **Alerts check**: Generates alerts for components with high demand and stale prices, trending components without prices, and components with no recent quotes
-- **Price updates**: Recalculates prices for all components using configured methods (median, weighted median, average)
-- **Usage counter reset**: Resets weekly and monthly usage counters for components
-- **Popularity score updates**: Recalculates popularity scores based on supplier quote activity
-
 ## Разработка

-# QuoteForge v1.0.3
-
-Дата релиза: 2026-02-06
-Тег: `v1.0.3`
-Диапазон изменений: `v1.0.2..v1.0.3`
-
-## Что нового
-
-- Добавлена страница управления проектами `/projects` с:
-  - датой и временем создания проекта;
-  - сортировкой по названию и дате создания;
-  - серверной пагинацией;
-  - фильтром по автору в заголовке таблицы.
-- Добавлена отдельная вкладка `Статус синхронизации` на уровне `Алерты / Компоненты / Прайслисты`.
-- Во вкладке статуса синхронизации отображаются:
-  - пользователь;
-  - версия приложения;
-  - статус (`онлайн` или относительное время последней синхронизации).
-
-## Изменения синхронизации
-
-- Реализован heartbeat синхронизации пользователей в MariaDB: `qt_pricelist_sync_status`.
-- Добавлен API `GET /api/sync/users-status` для UI статуса синхронизации.
-- Логика онлайн-статуса рассчитана от интервала фоновой синхронизации: `5 минут + 10%`.
-- В heartbeat фиксируется версия приложения (`app_version`).
-
-## Важные исправления
-
-- Исправлено восстановление отсутствующей серверной конфигурации при push обновлений.
-- Исправлено экранирование паролей в MySQL DSN в setup.
-- Улучшена логика запуска SQL-миграций на старте при отсутствии прав/необходимости.
-- Обновлена логика пересчета прайслистов через админский price-refresh.
-
-## Миграции и совместимость
-
-Добавлены SQL-миграции:
-
-- `migrations/010_add_pricelist_sync_status.sql`
-- `migrations/011_add_app_version_to_pricelist_sync_status.sql`
-
-Релиз совместим с предыдущей веткой `v1.0.x`; новая таблица синхронизации создается автоматически.
-
-## Коммиты в релизе
-
-- `b1b50ce` Add projects table controls and sync status tab with app version
-- `6ab1e98` sync: recover missing server config during update push
-- `a1d2192` Fix MySQL DSN escaping for setup passwords and clarify DB user setup
-- `a90c07c` update stale files list
-- `e9307c4` Apply remaining pricelist and local-first updates
-- `1b48401` Use admin price-refresh logic for pricelist recalculation
-- `4a86f7b` fix: skip startup sql migrations when not needed or no permissions

+# QuoteForge — План очистки (удаление admin pricing)
+
+Цель: убрать всё, что связано с администрированием цен, складскими справками, алертами.
+Оставить: конфигуратор, проекты, read-only просмотр прайслистов, sync, offline-first.
+
+---
+
+## 1. Удалить файлы
+
+- [x] `internal/handlers/pricing.go` (40.6KB) — весь admin pricing UI
+- [x] `internal/services/pricing/` — весь пакет расчёта цен
+- [x] `internal/services/pricelist/` — весь пакет управления прайслистами
+- [x] `internal/services/stock_import.go` — импорт складских справок
+- [x] `internal/services/alerts/` — весь пакет алертов
+- [x] `internal/warehouse/` — алгоритмы расчёта цен по складу
+- [x] `web/templates/admin_pricing.html` (109KB) — страница admin pricing
+- [x] `cmd/cron/` — cron jobs (cleanup-pricelists, update-prices, update-popularity)
+- [x] `cmd/importer/` — утилита импорта данных
+
+## 2. Упростить `internal/handlers/pricelist.go` (read-only)
+
+Read-only методы (List, Get, GetItems, GetLotNames, GetLatest) уже работают
+только через `h.localDB` (SQLite) без `pricelist.Service`.
+
+- [x] Убрать поле `service *pricelist.Service` из структуры `PricelistHandler`
+- [x] Изменить конструктор: `NewPricelistHandler(localDB *localdb.LocalDB)`
+- [x] Удалить write-методы: `Create()`, `CreateWithProgress()`, `Delete()`, `SetActive()`, `CanWrite()`
+- [x] Удалить метод `refreshLocalPricelistCacheFromServer()` (зависит от service)
+- [x] Удалить import `pricelist` пакета
+- [x] Оставить: `List()`, `Get()`, `GetItems()`, `GetLotNames()`, `GetLatest()`
+
+## 3. Упростить `cmd/qfs/main.go`
+
+- [x] Удалить создание сервисов: `pricingService`, `alertService`, `pricelistService`, `stockImportService`
+- [x] Удалить хэндлер: `pricingHandler`
+- [x] Изменить создание `pricelistHandler`: `NewPricelistHandler(local)` (без service)
+- [x] Удалить repositories: `priceRepo`, `alertRepo` (statsRepo оставить — nil-safe)
+- [x] Удалить все routes `/api/admin/pricing/*` (строки ~1407-1430)
+- [x] Из `/api/pricelists/*` оставить только read-only:
+  - `GET ""` (List), `GET "/latest"`, `GET "/:id"`, `GET "/:id/items"`, `GET "/:id/lots"`
+- [x] Удалить write routes: `POST ""`, `POST "/create-with-progress"`, `PATCH "/:id/active"`, `DELETE "/:id"`, `GET "/can-write"`
+- [x] Удалить web page `/admin/pricing`
+- [x] Исправить `/pricelists` — вместо redirect на admin/pricing сделать страницу
+- [x] В `QuoteService` конструкторе: передавать `nil` для `pricingService`
+- [x] Удалить imports: `pricing`, `pricelist`, `alerts` пакеты
+
+## 4. Упростить `handlers/web.go`
+
+- [x] Удалить из `simplePages`: `admin_pricing.html`
+- [x] Удалить метод: `AdminPricing()`
+- [x] Оставить все остальные методы включая `Pricelists()` и `PricelistDetail()`
+
+## 5. Упростить `base.html` (навигация)
+
+- [x] Убрать ссылку "Администратор цен"
+- [x] Добавить ссылку "Прайслисты" (на `/pricelists`)
+- [x] Оставить: "Мои проекты", "Прайслисты", sync indicator
+
+## 6. Sync — оставить полностью
+
+- Background worker: pull компоненты + прайслисты, push конфигурации
+- Все `/api/sync/*` endpoints остаются
+- Это ядро offline-first архитектуры
+
+## 7. Верификация
+
+- [x] `go build ./cmd/qfs` — компилируется
+- [x] `go vet ./...` — без ошибок
+- [ ] Запуск → `/configs` работает
+- [ ] `/pricelists` — read-only список работает
+- [ ] `/pricelists/:id` — детали работают
+- [ ] Sync с сервером работает
+- [ ] Нет ссылок на admin pricing в UI
+
+## 8. Обновить CLAUDE.md
+- [x] Убрать разделы про admin pricing, stock import, alerts, cron
+- [x] Обновить API endpoints список
+- [x] Обновить описание приложения
