feat: add qwen-code to providers that don't require initial configuration

- Added qwen-code to the list of providers in checkExistKey that can proceed without API keys
- This allows qwen-code to use its default OAuth path (~/.qwen/oauth_creds.json) without blocking the Welcome View
- Treats qwen-code similar to claude-code and other local authentication providers
