Summary

Describe the HTTP client scope and actual source installation. Provide one complete service example and an operation table. Keep application-versus-gateway authentication and sandbox cleanup visible. Move complete HTTP/authentication and configuration tables into bilingual docs/server-client and docs/configuration references without changing their contract.

Requested as a review and improvement of all eight repository READMEs. This PR covers only nodejs-sdk. Migration and maintenance details remain available through their owning guides. No runtime code or public API changes.
