Add transport and inventory update handling in BranchView component

- Implemented socket event listeners for 'transport_arrived' and 'inventory_updated' to manage real-time updates in the BranchView component.
- Enhanced event handling logic to refresh vehicle and inventory data based on the selected branch, improving user experience and data accuracy.
- Updated the component to ensure proper cleanup of socket listeners on component destruction, maintaining optimal performance.
