refactor: provider qwen-code separado com nome Qwen Code

- Cria provider 'qwen-code' separado do 'alibaba'
- Nome do provider: 'Qwen Code'
- Label do método OAuth: 'Qwen Code (qwen.ai OAuth)'
- Remove opção 'Importar do qwen-code'
- Remove '(OAuth)' dos nomes dos modelos
- Mantém apenas 2 modelos: qwen3-coder-plus e qwen3-coder-flash
