feat(qoder): fetch latest model + nút import model trên dashboard

Merge PR #1642 (decolua/9router) — chỉ lấy code + i18n, bỏ test/docs/package.json.

- qoder.js: bỏ guard QODER_MODEL_MAP cứng, resolve model_config qua dynamic API (hỗ trợ qmodel_latest không cần sửa code)
- dashboard page: thêm nút "Fetch Qoder Models" tự import model list vào aliases
- i18n zh-CN: thêm key cho nút fetch
