feat: Implementation of HWC 2.0

[jaime-iobermudez]

Description:

This pull request includes several improvements and refactorings across the Docker configuration, smart contracts, and test files. The main goals are to improve Docker build efficiency, clean up and standardize Solidity and TypeScript code, update dependencies, and enhance code readability in tests.

Docker and Development Environment Improvements:

• Refactored the backend/Dockerfile to separate copying of root files and backend source, set the working directory explicitly, and optimize dependency installation for both development and production builds. These changes streamline the Docker image build process and improve clarity. [1] [2] [3]
• Updated the backend/compose.yaml to use the correct context, Dockerfile path, working directory, and volumes, ensuring the backend service runs in the intended environment. Also updated the command to invoke the Nest CLI directly from the installed dependencies. [1] [2]

Smart Contract Refactoring and Cleanup:

• Refactored several Solidity contract methods to use single-line function signatures, improving code readability and consistency (BurnableFacet.sol, SupplierAdminFacet.sol, TokenOwnerStorageWrapper.sol, PrecompiledMock.sol). [1] [2] [3] [4] [5] [6] [7]
• Standardized string literals to use single quotes instead of double quotes in Solidity and TypeScript files for consistency. [1] [2] [3] [4]

Dependency and Configuration Updates:

• Updated hardhat and prettier-plugin-solidity to newer versions in contracts/package.json to keep the development environment up to date.
• Minor formatting improvements in TypeScript configuration files to enhance clarity.

Test Code Improvements:

• Improved formatting and consistency in test files, including better alignment, destructuring, and argument formatting. This enhances readability and maintainability of the test suite. [1] [2] [3] [4] [5] [6] [7] [8] [9] [10]

These changes collectively improve the project's maintainability, developer experience, and code quality.
