re-enable Prettier check for codex-cli in CI (#417)

This check was lost in https://github.com/openai/codex/pull/287. Both
the root folder and `codex-cli/` have their own `pnpm format` commands
that check the formatting of different things.

Also ran `pnpm format:fix` to fix the formatting violations that got in
while this was disabled in CI.
