P2 Badge Move app-token secrets out of this Dependabot event

This job only runs for dependabot[bot] PRs under pull_request_target, and GitHub's secret restrictions say that in this case workflow secrets are not available, aside from the read-only GITHUB_TOKEN. Because the new app-token step gets both required inputs from secrets.*, every patch/minor Dependabot PR will pass empty app credentials into actions/create-github-app-token and fail before the approve/merge steps; the app-token creation needs to run from a non-Dependabot-triggered handoff such as workflow_run/dispatch, or use credentials available in this event.
