[native] Backup testing button
Summary:
ENG-5699
This is the final testing task for rust native encryption. This diff rewires the current backup testing logic to use the native encryption (the existing logic already handles uploading and downloading backups from the backup service, but previously it called encryption from JS).
Depends on D10055
Test Plan:
- Enable backup encryption
- Test the restore procedure -> check that there are no errors
- Modify user store (e.g. relationship status) to trigger new backup upload
- Test the restore procedure again -> check that there are no errors
