test(ci): add temporary workflow_dispatch triggers for GITHUB_TOKEN testing

Add workflow_dispatch to both workflows so we can verify GITHUB_TOKEN
works on the feature branch before merging. These triggers will be
removed in the final commit.

- auto-label-issues.yml: adds issue_number input for dispatch testing
- stale.yml: adds workflow_dispatch + explicit permissions block
