The progress step used a binary `isRunning ? "in progress" : "completed"`
check. So when the backend rejected the restore (pre-flight validator
threw, path error, etc.) the wizard cheerfully rendered "Restore
completed" with 0% progress and no error context — the admin had to
SSH into the server and inspect `restore_runs.error_message` to find
out what happened.
Now reads the most recent row from `restoreStatus.history[0]` and
renders one of three states:
- running → blue text, progress bar updates
- succeeded → green tick + post-restore actions (existing behaviour)
- failed → red banner with the first line of error_message, and
a callout if was_rollback_attempted is true so the
admin knows the destination is safe to retry on top of.
Net: the wizard now tells the truth about what just happened.
