Add multi-guest management: per-booking roster, docs, guest autocomplete

- Migration 010: booking_guests table (roster per booking with passport data)
- Backend: /bookings/:id/guests CRUD — auto-links/creates guest profiles by passport
- Backend: /hotel-settings GET/PATCH for key-value settings (require_guest_docs)
- BookingDetailPanel: Гости tab with multi-guest list, inline add/edit form,
  guest autocomplete (debounced search in guests table), child/main badges,
  passport fields for adults, scan stub, require-docs warning
- SettingsPage: toggle "Обязательное заполнение документов гостей"
- Pass slug prop through CalendarPage → BookingCalendar → BookingDetailPanel
