docs(harnesses): copy polish on Lili's tweaks

- Fix broken `[H]` link in cloud Claude Code Related pages.
- Fix "OpenA credential type" typo in authentication.mdx.
- Clean up Anthropic Console URL (drop ?returnTo=/? query string).
- Capitalize "OpenAI Platform" to match "Anthropic Console".
- Restore --team in CLI examples so the follow-up sentence parses.
- Drop word-repeat in harnesses index ("harness from the harness dropdown").
- Switch backtick `Cloud Agent` to bold (UI/tab name per style guide).
- Reword dangling preposition in Codex available-models bullet.
- Trim trailing whitespace and a double-blank line.
