feat(app.js, i18n): add custom model management for Claude API

- Introduced UI elements for adding and managing custom models in the CLIProxyManager, including model name and alias inputs.
- Enhanced the display of model counts and badges in the provider item view.
- Updated internationalization strings to support new model management features in both English and Chinese.
