add booking request functionality for GENERAL customs contracts

- Create migration for booking_requests table with necessary fields and indexes.
- Implement BookingRequestRepository for database operations related to booking requests.
- Develop BookingRequestService to handle business logic for submitting, accepting, rejecting, and canceling booking requests.
- Create DTOs for creating booking requests and reviewing them.
- Define BookingRequest entity to map to the booking_requests table.
- Add UI components for managing shipment requests, including detail and list pages.
- Implement OperationDatePicker component for selecting available shipment days.
