feat: remove hardhat-dependency-compiler from contracts/test

Remove hardhat-dependency-compiler plugin as it's no longer needed.

The hardhat-dependency-compiler plugin was a historical workaround
that is no longer necessary for the current codebase structure.

Changes:
- Remove hardhat-dependency-compiler import and configuration from
  packages/contracts/test/hardhat.config.ts
- Remove getContractPaths() and findSolidityFiles() helper functions
- Remove hardhat-dependency-compiler dependency from
  packages/contracts/test/package.json
- Clean up hardhat-dependency-compiler directory reference from
  packages/contracts/package.json clean script
- Clean up unused imports (fs)
