feat: connect UsersPage and SettingsPage SMTP to API + extend user roles/fields

- Migration 034: extend users table with phone, position, active columns; add new roles (receptionist, accountant, security)
- Backend users.ts: accept phone/position on create, accept phone/position/active/role on update; managers can now assign all non-admin roles
- types/index.ts + api.ts: add phone, position, active to User type and users create/update payload types
- UsersPage: fix mapRole to handle all 5 roles, fix toStaffUser to use real phone/position/active from API, fix handleSave to pass all fields
- SettingsPage: load SMTP settings from hotelSettings API on mount, save SMTP on handleSave when section === 'notify'
