it is risen - add restore progress and backup/restore history

The watcher scripts now write live status and append-only run history onto the shared volume; the api exposes them via /shopdbbackups/status and /history. The restore modal shows an indeterminate spinner with phase labels, and two cards list backup and restore run records. Timestamps render in UTC to match the Zulu-stamped set ids, the history directory is excluded from the set list, and a stale-status guard stops a previous run's done phase from collapsing the spinner on the next restore.
