feat: Implement consolidated booking functionality

- Added support for viewing and managing consolidated bookings in BookingRequestDetailPage.
- Enhanced BookingRequestsPage to display paired bookings in a single row.
- Introduced pairedDecision method in bookings service to handle decisions for both halves of a consolidated pair.
- Updated contracts service to include methods for manual consolidation of odd-20ft bookings.
- Created new components for selecting and editing consolidation partners.
- Added tests for paired decision logic and manual consolidation scenarios.
- Updated UI to reflect changes in booking handling and provide user feedback for odd container counts.
