⚠️ Deprecation Notice: Removal of gRPC Gateway and Gateway Flag Renaming ⚠️

In an upcoming release, we will be deprecating the gRPC gateway and renaming several associated flags. This change will result in the removal of access to several internal APIs via REST, though the gRPC endpoints will remain unaffected. We strongly encourage systems to transition to using the beacon API endpoints moving forward. Please refer to PR #14089 for more details.
