* 🐳 feat: Expose enableServiceLinks in Helm Deployment templates (#11740)

Allow users to disable Kubernetes service link injection via enableServiceLinks
in both LibreChat and RAG API Helm charts. This prevents pod startup failures
caused by "argument list too long" errors in namespaces with many services.

* Update helm/librechat/templates/deployment.yaml



* Update helm/librechat-rag-api/templates/rag-deployment.yaml


* set enableServiceLinks default to true
