P2 Badge Move app credentials off this Dependabot trigger

For Dependabot PRs this job always runs under pull_request_target with github.event.pull_request.user.login == 'dependabot[bot]'; GitHub documents that in that context the workflow receives a read-only token and secrets are unavailable (see GitHub Docs: Dependabot on Actions). These secrets.* values are therefore empty for the only runs that reach this step, so actions/create-github-app-token cannot mint the token and the patch/minor auto-merge path stops before approval/merge. Use a trigger that can access the app credentials, such as a follow-up privileged workflow, or another supported credential source for Dependabot runs.
