feat(dashboard): sales chart + KPIs (как «Показатели» в МойСклад)

API: GET /api/sales/retail/stats?days=30 — возвращает:
- revenueToday + transactionsToday
- revenueThisMonth + transactionsThisMonth + avgTicketThisMonth
- revenuePrevMonth (для сравнения месяц-к-месяцу)
- series — массив дневных точек {bucket, revenue, transactions} с заполнением
  пустых дней нулями (чтобы линия графика была непрерывной)
- считает только проведённые чеки (Status == Posted)

Web:
- recharts добавлен (3.8.1)
- SalesChart компонент: AreaChart с градиент-заливкой брендового зелёного,
  ось X — дни (DD.MM), ось Y — выручка, tooltip с числами и валютой
- DashboardPage пересобран под продажи как первичную инфу:
  - 4 KPI-карточки сверху: выручка сегодня, выручка за месяц (с дельтой
    к прошлому месяцу), средний чек, прошлый месяц
  - график за 30 дней с empty-state когда чеков нет
  - Каталог теперь второстепенный (мелкие карточки внизу)

Empty-state: если за 30 дней не было ни одной продажи — показываем
"График появится когда появятся первые продажи" вместо плоской линии.
