Updated RefreshResponse field names and token handling

The `RefreshResponse` data class has been updated to use `access_token` and `refresh_token` to match the API response. Consequently, `MainViewModel` now uses these updated field names when saving new tokens to storage. Debug print statements for access and refresh tokens have also been removed.
