- Add upsertGuestFromBooking() service — creates or updates guest record
when a booking is made (matches by email/phone, creates if not found)
- Integrated into bookings.ts (manual PMS bookings) and publicWidget.ts
(online widget bookings)
- Name parsed as Russian format: "Фамилия Имя [Отчество]"
- Non-throwing: booking creation never fails due to guest upsert errors
