feat: persist custom endpoints to settings.json

- Extend AppSettings to store custom endpoints for Claude and Codex
- Add Tauri commands: get/add/remove/update custom endpoints
- Update frontend API with endpoint persistence methods
- Modify EndpointSpeedTest to load/save custom endpoints via API
- Track endpoint last used time for future sorting/cleanup
- Store endpoints per app type in settings.json instead of localStorage
