- `/` is now the main menu; orders/receipts page moved to `/receipts`
- Module registry (features/menu/modules.ts) drives both the menu tiles
and route guards (ModuleRoute); admin sees every module
- Menu: module search with Ctrl+K, profile with logout, responsive grid,
palette matching the login page
- «← Головне меню» link on receipts and cash registers pages;
«Каси» moved from the receipts toolbar into the menu
