Fixes a race condition when forwarding multiple ports to a single pod. Root cause was concurrent access to an unguarded `auditSent` map in the forwarder `portForward()` function. Changes: `lib/kube/proxy/forwarder.go` - Added mutex for `auditSent` map in `portForward()` `lib/kube/proxy/portforward_test.go` - Added mock test for Kubernetes forwarding multiple ports `lib/kube/proxy/testing/kube_server/kube_mock.go` - Revised mock server `portforward` function to process each stream in a goroutine `lib/kube/proxy/utils_test.go` - Updated test context `startKubeServices` function to allow and expect `net.ErrClosed` Fixes #57242
