i18n: localize provider preset names and sorting logic

- Replace hardcoded Chinese preset names with English versions (Claude Official, Zhipu GLM, Qwen Coder, ModelScope, Codex Official, KAT-Coder)
- Update ProviderList sorting to use locale-aware comparison based on current language (zh-CN for Chinese, en-US for English)
- Reorder presets: move KAT-Coder before PackyCode for better grouping
