fix: resolve Docker build and configuration issues

- Fix Docker build error by copying README.md (required by pyproject.toml)
- Change CMD to ENTRYPOINT to properly handle MCP arguments
- Remove unused EXPOSE 8000 port (MCP uses stdio, not HTTP)
- Update README comment to clarify Docker image is for local builds
- Docker build and run now work correctly for MCP integration

Fixes: 'docker build -t pia-mcp-server:latest .' command
