Simplify create-twenty-app command (#20512)

## Simplify `create-twenty-app` for zero-interaction use

Makes `npx create-twenty-app@latest my-app` a fully non-interactive,
single-command experience suitable for automated environments (Codex,
Claude plugins).

  ### Changes

- **Remove all interactive prompts** — app name, display name,
description, and scaffold confirmation are now derived from CLI args
with sensible defaults. `inquirer` dependency removed
   entirely.
- **Replace OAuth with API key auth** — use the seeded dev API key
(`DEV_API_KEY`) to authenticate against the Docker instance as
`tim@apple.dev`, eliminating the browser-based OAuth
  flow.
- **Docker-first with early validation** — check Docker is installed
before scaffolding; if missing, print the install URL and exit. Detect
alternative runtimes (Podman, nerdctl).
- **Parallel image pull** — `docker pull` runs in the background during
scaffold + dependency install, saving 10-30s on typical runs.
- **Always pull latest image** — ensures the dev server is up-to-date on
every run.
- **Stop detecting port 3000** — only check port 2020 (Docker instance).
- **Update CLI flags** — remove `--skip-local-instance` and `--yes`; add
`--skip-docker`.
- **Update CI workflows and docs** — align e2e workflows, package
README, and template README/cd.yml with the new flow.
