feat: minibar — category dropdown, учёт остатков (приходы/списания/инвентаризация/отчёт)

- MinibarSettingsPage: поле категории → выпадающий список с существующими + «Новая...»
- Кнопка «Учёт и остатки» ведёт на /settings/minibar/stock
- MinibarStockPage: 5 вкладок — Остатки, Приходы, Списания, Инвентаризация, Отчёт
- api.ts: добавлены методы и типы для stock/receipts/writeoffs/inventory/report
