- YooKassa service for hold/capture/cancel payments
- Frontend: ChecklistSettingsPage, MinibarSettingsPage, DepositSettingsPage
- HousekeepingPage: task cards now show checklist + minibar panel with checkboxes and quantity buttons
- BookingModal: minibar charges summary + deposit management (cash/YooKassa/release) for existing bookings
- Sidebar + App.tsx: new routes /settings/checklists, /settings/minibar, /settings/deposit
