Fix booking: use correct BookReservation endpoint + price from selected dates

- Fixed endpoint: /Reservations/BookReservation/book (was /Reservations/Book)
- bookReservation now takes (propertyId, startDate, endDate) params
- Pricing updates dynamically based on selected date range
- Deposit read from API response instead of hardcoded
- Removed demo fallback that always showed success
