Integrate Backend with Hyperledger Fabric for PoD Events #33
Description
Develop the service layer in our backend that connects to the v1 Hyperledger Fabric network. Create a function that allows our system to invoke the "Proof of Delivery" smart contract, writing a permanent, trusted record of a completed shipment to the blockchain.
Suggestions: This is a critical integration. It will require using the Hyperledger Fabric SDK for Node.js or Go. The work must be heavily tested and documented, as blockchain transactions are immutable.
