fix(ci): grant commitlint workflow pull-requests:read permission

wagoid/commitlint-github-action calls the GitHub API to list a PR's commits. Without pull-requests:read it fails with: error trying to get list of pull request's commits / Resource not accessible by integration. Adding the permission unblocks dependabot PRs that hit this on the recreate. Mirrors the working config in Infra.BauxTP.com. Surfaced by /jc-coding-fleet-driver Phase D follow-up 2026-04-28.
