* fix: add guest limits and rate limiting to booking-guests endpoint - Add ArrayMaxSize(10) validation to limit guests per request to 10 - Add aggressive rate limiting (5 requests/minute) via @Throttle decorator - Add total guest limit check (max 30 guests per booking) to prevent abuse - Update API documentation to reflect new limits This prevents scammers from using the endpoint to send spam emails to hundreds of guests through our system.
