GITOPS-11176: return null from rollout decorator so Topology URL links render

[dipakkarde]

Summary

Workloads → Topology should show the Route/Open URL decorator on workloads (Deployments, etc.) when gitops-plugin is enabled.

The plugin registers a Topology decorator on upperRight, the same corner as that Route decorator. For workload nodes it returned an empty fragment (<></>). Topology uses the first truthy decorator in that corner, so the fragment hid the Route icon.

Return null so the Route decorator can render.

Fixes: https://issues.redhat.com/browse/GITOPS-11176

Test plan

• gitops-plugin enabled: Deployment with a Route shows the Topology Route/Open URL decorator

Made with Cursor
