Add calendar-based booking system: accounts, availability, admin calendar

- Customer accounts (separate auth collection) with /konto area - Availability + AvailabilityOverrides collections driving real slot calculation - BookingRequests with race-safe confirmation (Postgres advisory lock + transaction) - Booking emails (request received, admin notify, confirmed, rejected, alternative proposed/accepted, cancelled) - Confirmed online bookings auto-create a private linked video-call Event - Custom Payload admin calendar view (month grid + day schedule) - Wired booking widget into offer pages and /termin-buchen
