Subject: [PATCH] Add save to device option for Polycentric profile export

- Add dialog with two options: Share or Save to Device
- Implement saveToDevice method using MediaStore API to save to Downloads folder
- Add necessary string resources for the new UI elements
- Use UIDialogs.showDialog with Action and ActionStyle for proper dialog handling
- Add ContentValues and MediaStore imports for file saving functionality

Users can now choose to either share the exported profile file or save it directly to their device's Downloads folder for later use.
