Система теперь корректно работает на узких экранах (<768px):

- AppLayout: на мобиле фиксированный sidebar заменён hamburger-меню
  (Menu icon) + off-canvas drawer с overlay. На md+ — прежний sidebar.
- ProductsPage: дерево групп тоже превращается в drawer на мобиле,
  кнопка «Группы» рядом с заголовком; фильтры flex-wrap.
- Modal: на мобиле (<sm) разворачивается на весь экран (items-stretch,
  min-h-full, убраны скругления и верхний отступ).
- DataTable: мин-ширина 640px + whitespace-nowrap в заголовках, уменьшен
  горизонтальный padding на мобиле. Родительский overflow-auto даёт
  плавный горизонтальный скролл.
- PageHeader/ListPageShell: flex-wrap, меньший padding на мобиле.
- SearchBar: flex-1 на узких (занимает доступное место), фикс 256px на sm+.
- ProductEditPage Grid helper: 3/4 колонки теперь grid-cols-1 sm: 2
  md: 3/4 — поля не слипаются на телефоне.
- ProductEditPage/Supply/RetailSale/Dashboard/OrganizationSettings:
  отступы p-3 sm:p-6, grid grid-cols-2 на страну/валюту → 1 col на мобиле.
