docs: clarify unified Qwen OAuth experience across ALL platforms

- All platforms now have IDENTICAL Qwen OAuth integration
- ZeroClaw: native provider (built-in)
- Others: OpenAI-compatible + auto-refresh script
- Same result: FREE tier, auto refresh, same credentials file
- Updated platform table to show "Full" support (not just "Import")

User experience is now identical regardless of platform choice.
