docs(zai): align setup guide with runtime defaults

- remove trailing whitespace in .env.example Z.AI block
- align documented model defaults/options with current onboard/provider behavior
- keep this PR docs-focused by reverting incidental workflow edits

+- Try `glm-4-flash` for lower latency and higher quota tolerance
