Backend ABI Registry: Automate sync with contract

[EDOHWARES]

Description

Currently, the ABI in the backend-abi-registry needs to be manually updated when the contract changes. We need an automated script.

Requirements

• Write a script in /scripts to copy the latest compiled WASM and JSON ABI to the registry.
• Add this script to the Makefile or package.json.
