feat(api): enhance statistics storage management with scope options

- Introduced a new type `StatisticsStorageScope` to specify the scope for clearing statistics.
- Updated the `clearStatisticsStorage` API method to accept a scope parameter, allowing for selective clearing of detailed records or all statistics.
- Modified the demo API to handle the new scope parameter appropriately.
- Updated the SettingsPage component to include a selection for clearing scope, enhancing user control over statistics management.
- Added new translations for the updated messages related to statistics clearing in both English and Chinese.
