- UsersPage: add "Роли и права" tab with per-module permission editor per role; create/delete custom roles
- LoyaltyPage: add "Правила начисления" tab with togglable accrual rules editor; add "Ручное начисление" tab with guest search by name/phone/email, add/deduct points with reason and history; fix banner text (HotelSync is a PMS, not a hotel chain)
