feat: automatically switch to imported mode after successful import

- Add importedModes field to ImportResult interface to track imported mode slugs
- Modify importModeWithRules method to collect and return imported mode slugs
- Update webview message handler to automatically switch to first imported mode
- Update ModesView.tsx to handle successful import with mode switching

Fixes #6491
