📊 Phase 2 Backend Summary

• Authentication: 100% complete
• Organization & User Management: 100% complete
• Booking Domain & API: 100% complete
• Email Service: 100% complete
• PDF Generation: 100% complete
• Document Storage: 100% complete
• Post-Booking Automation: 100% complete

🚀 How Post-Booking Automation Works

When a booking is created:

1. BookingService creates the booking entity
2. BookingAutomationService.executePostBookingTasks() is called
3. Fetches user and rate quote details
4. Generates booking confirmation PDF using PdfPort
5. Uploads PDF to S3 using StoragePort (bookings/{bookingId}/{bookingNumber}.pdf)
6. Sends confirmation email with PDF attachment using EmailPort
7. Logs success/failure (non-blocking - won't fail booking if email/PDF fails)
