Persist NetworkPolicy failures and continue stopping stopped workspaces.

SyncNetworkPolicy runs before the deferred status update. A FailError can therefore update only the in-memory status and return before the failure reaches the workspace. The API server can reject invalid NetworkPolicy fields, and SyncObjectWithCluster maps those errors to FailError.

The same return occurs before the stopped-workspace branch. A NetworkPolicy failure can prevent stopWorkspace from running.

Suggested fix 
 	err = networkpolicy.SyncNetworkPolicy(workspace, clusterAPI)
-	if shouldReturn, reconcileResult, reconcileErr := r.checkDWError(workspace, err, "Error provisioning network policy", metrics.ReasonInfrastructureFailure, reqLogger, &reconcileStatus); shouldReturn {
-		return reconcileResult, reconcileErr
+	if !workspace.Spec.Started {
+		if err != nil {
+			reqLogger.Error(err, "Error syncing network policy while stopping workspace")
+		}
+	} else if shouldReturn, reconcileResult, reconcileErr := r.checkDWError(workspace, err, "Error provisioning network policy", metrics.ReasonInfrastructureFailure, reqLogger, &reconcileStatus); shouldReturn {
+		if _, ok := err.(*dwerrors.FailError); ok {
+			return r.updateWorkspaceStatus(workspace, reqLogger, &reconcileStatus, reconcileResult, reconcileErr)
+		}
+		return reconcileResult, reconcileErr
 	}

In `@controllers/workspace/devworkspace_controller.go` around lines 171 - 177,
Update the SyncNetworkPolicy error handling so FailError status is persisted
through updateWorkspaceStatus before returning, and so a NetworkPolicy sync
failure does not prevent the stopped-workspace flow from reaching stopWorkspace;
log the failure and continue when workspace.Spec.Started is false.
