Refactor CDS compilation within actions workflows

Replace platform-specific shell logic in cds-compilation-for-actions
scripts with a cross-platform Node.js script (compile-test-cds.mjs)
that reuses CDS extractor functions via a new esbuild library bundle.
The .cmd and .sh wrappers now delegate entirely to `node`.
