New Deno Deploy docs: production-branch location, disabling preview deploys, and CI --token auth are missing/outdated

Setting up a new app on the new Deno Deploy (`console.deno.com`) — a scheduled `Deno.cron` service deployed from CI — I hit several documentation gaps where the docs were vague or didn't match the current dashboard. Sharing as constructive feedback:

1. **Production branch location.** Docs imply the production branch is set under a "Git" tab in app Settings, but in the current UI the branch selector is on the app **Settings page directly** — there is no "Git" tab. The pointer sent me hunting.

2. **Entrypoint field is hidden.** During app creation the required **Entry point** field is collapsed behind an **"Edit app configuration"** button. This isn't documented and is easy to miss that the field exists.

3. **No documented way to disable preview/branch deployments.** With the GitHub integration, every branch builds (production branch → production, others → preview) and each PR gets a `deploy//` status check. For a service that should deploy **only from `main`**, there's no documented setting to turn off preview/branch deploys or the PR status check — only per-commit `[skip deploy]`. Please document whether this is configurable.

4. **CI/CD token auth is undocumented.** The CLI reference states "the CLI will prompt for authentication" and doesn't mention non-interactive auth. I only discovered `deno deploy --token ` by running `deno deploy --help`. Please document `--token` (and any env-var equivalent) for CI/CD use.

5. **General:** the new-platform UI docs lag the actual dashboard — exact field labels and a screenshot-level "create app from GitHub" walkthrough would help a lot.

Versions: Deno 2.8.2, `@deno/deploy` 0.0.99, `console.deno.com` (new platform), June 2026.

**Suggestion:** a current "Deploy from GitHub via the dashboard" walkthrough with real labels, the production-branch location, a preview-deploy toggle (or how to deploy only the production branch), and a CI/CD section covering `--token`.
