Subject: [PATCH] Refactor booking process in BookNowPage to integrate
 appointment creation via useAppointments hook. Enhance form submission logic
 to check user authentication before proceeding. Update API endpoint
 configurations for appointment management, including available dates and user
 appointments. Improve error handling and user feedback with toast
 notifications.
