feat(test/label): add post-comment input to control PR commenting

Add a `post-comment` input (default: `true`, not required) to both
`test/label/done/added` and `test/label/done/remove` actions. When set
to `false`, all PR comment posting is skipped while label logic runs
unchanged.

Milestone: [DevOps] CI/CD Foundations & Release Pipelines (v1 working)
