/**
* Regression coverage for the Christopher Finks / Issue 1 restore data-loss
* bug. Before the fix, SettingsController::postRestore called Artisan::call
* ('db:wipe') before verifying the archive or taking a pre-restore backup,
* so an invalid/corrupt/foreign archive destroyed the pre-existing database
* while the flow still reported success.
*
* These tests exercise the two guards the fix added:
*
* 1. The archive is validated with ZipArchive::open() BEFORE db:wipe runs.
* A malformed zip therefore leaves the current database untouched.
* 2. A pre-restore backup is taken BEFORE db:wipe runs. If snipeit:backup
* fails, restore aborts before touching the database.
