Pull Request Overview

Adds a default OpenShift server endpoint and updates the pr-close workflow steps to use this default when the oc_server secret isn’t provided.

• Introduce DEFAULT_OC_SERVER as a workflow-level environment variable
• Update each oc_server input to fall back to DEFAULT_OC_SERVER if the secret is unset

• [nitpick] The fallback expression for oc_server is duplicated across multiple steps. Consider defining a single workflow or job-level env var (e.g., OC_SERVER) that applies this fallback once and reuse it to reduce duplication and simplify future updates.

          oc_server: ${{ secrets.oc_server || env.DEFAULT_OC_SERVER }}

• [nitpick] It could be helpful to add a brief comment above DEFAULT_OC_SERVER explaining its role and when it will be used as a fallback to improve clarity for future maintainers.
