Summary

This PR improves Docker build performance by optimizing caching for npm install.

Changes

• Separated COPY steps for all relevant package.json and package-lock.json files from workspaces.
• Moved full source COPY after npm install.
• This allows Docker to reuse cached layers if dependencies have not changed.

Benefits

• Significantly faster rebuilds when source files change but dependencies remain the same.
• Reduced image build times and more efficient CI/CD pipeline performance.
• Aligns with Docker best practices for layer caching.

No functionality changes introduced.
