fix(engine): check + log restore-script remote upload (no longer silent)

The standalone restore script was uploaded to each remote with the result
discarded and nothing logged, so a failed second upload left the restore script
missing from the remote with no warning while the archive still recorded
'complete'. Capture the result: log success, and on failure set uploadFailed
(-> warning status) and log the reason.

Fixes #226

+### Fixed
+- Remote upload: the standalone restore script upload is no longer silent — its result is now checked and logged, and a failed restore-script upload marks the backup as `warning` (previously the result was discarded, so a missing restore script on the remote went unreported while the archive still showed success).
